Abstract
N-(heterocyclicaminocarbonyl)arylsulfonamides in which the aryl radical is substituted in the 2-position by a carboxy radical, ester, thioester, or amide thereof; e.g. N-[(4,6-dimethylpyrimidin-2-yl)-aminocarbonyl]-2-methoxycarbonylbenzenesulfonamide or N-[(4,6-dimethoxy-1,3,5-triazin-2-yl)aminocarbonyl]-2-methoxycarbonylbenzenesulfonamide; are useful for the regulation of plant growth and as pre-emergence and post-emergence herbicides.
Description

BACKGROUND OF THE INVENTION
This invention relates to novel N-(heterocyclicaminocarbonyl)arylsulfonamides in which the aryl radical is substituted by a carboxyl radical, ester, thioester or amide thereof. The compounds of this invention and their agriculturally suitable salts, are useful as agricultural chemicals, e.g. plant growth regulants and herbicides.
Netherlands Pat. No. 121,788, published Sept. 15, 1966, discloses the preparation compounds of the following Formula and their use as general or selective herbicides: ##STR1## wherein
R.sub.1 and R.sub.2 may independently be alkyl of 1-4 carbon atoms; and
R.sub.3 and R.sub.4 may independently be hydrogen, chlorine or alkyl of 1-4 carbon atoms.
U.S. Pat. No. 3,637,366 discloses compounds having the formula: ##STR2## wherein
R.sub.1 is hydrogen or lower saturated aliphatic acyl and
R.sub.2 is hydrogen, 2-pyrimidinyl, pyridyl, amidino, acetyl or carbamoyl.
The disclosed compounds are said to provide control of crabgrass, cress, endive, clover and Poa annua.
French Pat. No. 1,468,747 discloses the following para-substituted phenylsulfonamides as being useful as antidiabetic agents: ##STR3## wherein R=H, halogen, CF.sub.3 or alkyl.
Logemann et al. Chem Ab., 53, 18052 g (1959), disclose a number of sulfonamides including uracil derivatives and those having the formula: ##STR4## wherein
R is butyl, phenyl, or ##STR5## and
R.sub.1 is hydrogen or methyl.
When tested for hypoglycemic effect in rats (oral doses of 25 mg/100 g), the compounds in which R is butyl and phenyl were most potent. The others were of low potency or inactive.
Wojciechowski, J. Acta. Polon. Pharm 19, p. 121-5 (1962) [Chem. Ab., 59 1633 e] describes the synthesis of N-[(2,6-dimethoxypyrimidin-4-yl)aminocarbonyl]-4-methylbenzenesulfonamide: ##STR6## Based upon similarity to a known compound, the author speculated that the foregoing compound might have a hypoglycemic activity.
Substituted-pyrimidinyl sulfonylureas of the following formula, which are also para-substituted on the phenyl ring, are disclosed in Farmco Ed. Sci., 12, 586 (1957) [Chem. Ab., 53, 18052 g (1959]: ##STR7## wherein R=H or CH.sub.3.
The presence of undesired vegetation causes substantial damage to useful crops, especially agricultural products that satisfy man's basic food and fiber needs, such as cotton, rice, corn, wheat, and the like. The current population explosion and concomitant world food and fiber shortage demand improvements in the efficiency of producing these crops. Preventing or minimizing loss of a portion of such valuable crops by killing, or inhibiting the growth of undesired vegetation is one way of improving this efficiency. A wide variety of materials useful for killing or inhibiting (controlling) the growth of undesired vegetation is available; such materials are commonly referred to as herbicides. The need still exists however, for more effective herbicides.

Synthesis
Many of the compounds of Formula I are prepared as shown in Equation 3 by the reaction of an appropriately substituted o-carbonylbenzenesulfonyl isocyanate or isothiocyanate with an appropriate aminopyrimidine or aminotriazine. These compounds of Formula I can be converted to other compounds of Formula I as will be shown in subsequent equations. Thus, o-carbonylbenzenesulfonyl isocyanates and sulfonyl isothiocyanates are important intermediates for the preparation of the compounds of this invention. Therefore, the synthesis of these is described in Equations 1 and 2.
Equation 1 ##STR46##
A mixture of the appropriate sulfonamide, e.g. an o-alkoxycarbonyl benzenesulfonamide IIa such as the methyl ester, which is known in the art, an alkyl isocyanate such as butyl isocyanate and a catalytic amount of 1,4-diaza[2,2,2]bicyclooctane (DABCO) in xylene or other inert solvent of sufficiently high boiling point (e.g. >135.degree.) is heated to approximately 135.degree.. Phosgene is added to the mixture until an excess of phosgene is present as indicated by a drop in the boiling point. (The mixture is heated further to drive off the excess phosgene). After the mixture is cooled and filtered to remove a small amount of insoluble by-products, the solvent and alkyl isocyanate are distilled off in-vacuo leaving a residue which is the crude sulfonyl isocyanate II.

R.sub.3 is H, Cl, Br or CH.sub.3
Where W=S in Formula I the useful sulfonylisothiocyanate intermediates are prepared according to Equations 2 and 2'.
Equation 2 ##STR49##
The o-carbonyl substituted sulfonamide is dissolved in dimethylformamide (DMF) with an equivalent amount of carbon disulfide and two equivalents of potassium hydroxide are added portionwise at room temperature. The mixture is stirred for 1-8 hours and diluted with ethylacetate, ethyl ether or similar aprotic solvent to cause the dipotassium salt of the dithiocarbamic acid to precipitate. The salt is isolated, dried and suspended in an inert solvent such as xylene, benzene, carbon tetrachloride or methylene chloride. Phosgene is added to the stirred suspension at below room temperature and the mixture stirred for 1-3 hours. In place of phosgene, a chloroformic ester (e.g. methyl chloroformate), phosphoruspentachloride sulfuryl chloride or thionyl chloride can be used.
The sulfonylisothiocyanate which is formed is usually soluble in the solvent and is isolated by filtering off the inorganic potassium chloride and concentrating the filtrate. These isothiocyanates tend to be unstable and dimerize readily, (Equation 2') however, the dimers can be used
Equation 2' ##STR50## in the same manner as the parent isothiocyanates for the purposes of this invention.
The synthetic method chosen for the preparation of compounds of Formula I depends largely on the substituents R and R.sub.4. As shown in Equation 3, compounds of Formula I, wherein Q, R, R.sub.2 and R.sub.3 are as defined for Equation 1, are conveniently prepared by reacting an appropriately substituted carbonylbenzenesulfonyl isocyanate or isothiocyanate of Formula IIb with an appropriately substituted aminopyrimidine or aminotriazine of Formula III:
Equation 3 ##STR51##
The reaction of Equation 3 is best carried out in inert aprotic organic solvents such as methylene chloride, tetrahydrofuran or acetonitrile, at ambient pressure and temperature. The mode of addition is not critical; however, it is often convenient to add the sulfonyl isocyanate or isothiocyanate to a stirred suspension of amine III. Since such isocyanates and isothiocyanates are liquids, low melting solids or are readily soluble in solvents such as those listed above, their addition can be easily controlled.
The reaction is generally exothermic. In some cases, the desired product is soluble in the warm reaction medium and on cooling crystallizes in pure form. Other products which are soluble in the reaction medium are isolated by evaporation of the solvent, trituration of the solid residue with solvents such as 1-chlorobutane or ethyl ether, and filtration.
As shown in Equation 3A compounds of Formula Ia, wherein R is not H or M, W is S and R.sub.5 is H, are alternatively prepared by the reaction of an appropriately substituted o-carbonylbenzenesulfonamide with the appropriate triazine or pyrimidine isothiocyanate of formula IIIA.
Equation 3A ##STR52##
The reaction of Equation 3A is best carried out by dissolving or suspending the sulfonamide and isothiocyanate in a polar solvent such as acetone, acetonitrile, ethyl acetate or methylethylketone, adding an equivalent of a base such as potassium carbonate and stirring the mixture at ambient temperature up to the reflux temperature for one to twenty-four hours. In some cases, the product precipitates from the reaction mixture and can be removed by filtration. The product is stirred in dilute mineral acid, filtered and washed with cold water. If the product does not precipitate from the reaction mixture it can be isolated by evaporation of the solvent, trituration of the residue with dilute mineral acid and filtering off the insoluble product.
The heterocyclic isothiocyanates which are used in the procedure of Equation 3A are prepared, for example, according to the method of Japan patent application Pub: Kokai 51-143686, June 5, 1976, or that of W. Abraham and G. Barnikow Tetrahedron 29, 691-7 (1973).
As shown in Equation 4, compounds of Formula I, wherein Q is O, S or ##STR53## and R is as defined for Equation 1 R.sub.4 is methyl and W is O, can be prepared by methylation of salts IV wherein M is an alkali metal cation such as sodium (derived from compounds of Formula I wherein R.sub.4 is hydrogen):
Equation 4 ##STR54## X being an incipient anion and n being an integer corresponding to the valence of X.
The reaction of Equation 4 is best carried out in aprotic organic solvents such as tetrahydrofuran, dimethylformamide, or dimethylacetamide, at ambient pressure and temperature. Methylating agents V, such as dimethyl sulfate or methyl iodide, can be employed. The desired product can be isolated by pouring the reaction mixture into water and filtering off the precipitated solid.
As shown in Equation 5, compounds of Formula Ic, wherein Q is O, S or ##STR55## R and R.sub.4 are as defined for Equation 4, can also be prepared by the reaction of an appropriately substituted sulfonyl-N-methylcarbamyl chloride or sulfonyl-N-methylthiocarbamyl chloride of Formula VI with an appropriate aminopyrimidine or aminotriazine of Formula III:
Equation 5 ##STR56##
The preparation of ureas and thioureas, like those of Formula Ic, from amines and carbamyl chlorides and thiocarbamyl chlorides is well known to the art. The reaction can best be carried out by adding equivalent amounts of the chloride VI and amine III to an inert organic solvent, such as tetrahydrofuran, xylene, or methylene chloride, in the presence of an acid acceptor, such as triethylamine, pyridine, or sodium carbonate employing temperatures from 20.degree.-130.degree.. Soluble products can be isolated by filtering off the precipitated salts and concentration of the filtrate. Insoluble products can be filtered off and washed free of salts with water.
The chlorides of Formula VI can be prepared by phosgenation or thiophosgenation of N-alkylsulfonamide salts. The sulfonamide salt is added to an excess of phosgene or thiophosgene in an inert organic solvent, such as tetrahydrofuran, toluene, or xylene, whereupon, after removal of the excess phosgene, the chloride VI can be isolated or reacted in situ with the amine III.
Compounds of Formula Ie, wherein R is --H, can be prepared by hydrolysis of esters of Formula Id wherein R is C.sub.1 -C.sub.12 alkyl. As shown in Equation 6, alkali metal base catalyzed hydrolysis in aqueous methanol produces the alkali metal carboxylate from which the carboxylic acid is obtained by treatment with mineral acids such as HCl:
Equation 6 ##STR57##
The reaction of Equation 6 is best carried out in a solution containing the compound being hydrolyzed, 2 to 10 parts of methanol, 10-50 parts of water and 2-10 equivalents of a base such as sodium or potassium hydroxide maintaining the temperature at 30.degree.-90.degree. C. for 3-24 hours. The reaction yields the soluble alkali metal salt of the carboxylic acid, which is suitable for the purposes of this invention. Conversion of these salts to the acid form is easily carried out by addition to the reaction medium of strong mineral acids, such as hydrochloric or sulfuric acid, causing the desired carboxylic acids to precipitate from solution.
Compounds wherein W and Q are O and R is H can be converted to compounds of this invention where R is a higher alkyl or substituted hydrocarbyl group, as already disclosed herein, by the reaction of salts of the parent acid (R=H) with R-Halogen as shown in Equation 6A.
Equation 6A ##STR58##
The reaction of Example 6A is of use where the intermediate compound R-Halogen contains a readily replaceable halogen as is the case for substituted or unsubstituted allylic or benzylic halides, .alpha.-halonitriles, or .alpha.-halocarbonyl compounds.
The procedure of Equation 6A is best carried out in inert polar solvents such as tetrahydrofuran, acetonitrile or acetone by combining the appropriately substituted carboxylic acid and base such as triethylamine or 1,4-diaza[2,2,2]bicyclooctane adding the appropriate halide and heating the mixture to reflux with stirring for 1 to 16 hours. The reaction mixture can be evaporated to dryness and the residue triturated with water, filtered and washed with water to separate the desired product from the water soluble salt.
Certain compounds of Formula I, wherein Q is oxygen, are more conveniently prepared by reaction of the silver salt of the carboxylic acid and the appropriate R group containing a suitable leaving group such as iodide. Thus, a substituted iodobenzene is reacted with the silver carboxylate as in Equation 6B
Equation 6B ##STR59## in a suitable solvent such as acetonitrile between 0.degree. and 80.degree. for 1-6 hours.
Esters where R is C.sub.3 -C.sub.9 alkynyl are also conveniently prepared by this method.
The silver salt is prepared by adding an excess of silver nitrate to an aqueous solution of the sodium carboxylate and filtering the precipitate and washing with water.
Compounds of Formula I wherein Y of group R.sub.1 contains ##STR60## and L is OH can be prepared according to the procedure of Equation 6C wherein R, R.sub.2, R.sub.3, Q, R.sub.4, W, X and R.sub.5 are as previously defined.
Equation 6C ##STR61##
The reaction of Equation 6C is best carried out by suspending the compound being hydrolyzed in 10 to 100 parts of water with enough of a base such as sodium hydroxide or potassium hydroxide to obtain a pH of 10 to 14, ideally, a pH of 12, heating until a clear solution is obtained and then adjusting the pH to 1-3, preferably 3. The product is thus caused to precipitate in some instances and can be removed by filtration and it can be extracted into a polar organic solvent such as methylene chloride and isolated by evaporation of the solvent.
When Q is NR.sub.6, the compounds can be prepared from the esters of this invention where R is C.sub.1 -C.sub.14 (preferably C.sub.1) by the reaction of the esters with dialkylaluminum-N-alkylamide derivatives according to Equation 7, R, R.sub.1, R.sub.2, R.sub.3 and R.sub.6 being as previously defined.
Equation 7 ##STR62##
The intermediate alkylaminoaluminum compounds prepared according to A. Basha, M. Lipton and S. W. Weinreb, Tetrahedron Letters 4171 (1977), are co-mingled with a suspension of the esters in toluene or similar inert solvent and the mixture is refluxed for one to six hours. The product can be isolated by evaporation of the solvent toluene, adding methylene chloride and aqueous hydrochloric acid to decompose the residual reaction mass and extracting the desired product into methylene chloride. Evaporation of the methylene chloride yields the desired product in sufficiently pure form for the purpose of this invention.
Compounds of formula IId, wherein Q is NR.sub.6 and R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are as previously defined in the general formula, which are useful as intermediates in Equation 3A, are prepared as shown in Equation 7A.
Equation 7A ##STR63## The conditions described for Equation 7 are suitable for the conversion of the esters of formula IIc to the amides IId as shown in Equation 7A.
The products of Equation 7A are especially useful for the preparation of compounds of formula Ia wherein Y has an ester substituent CO.sub.2 (C.sub.1 -C.sub.6), by the route described in Equation 3A.
When Q is S, these compounds can be prepared from the esters of this invention wherein QR is C.sub.1 -C.sub.4 alkoxy (preferably C.sub.1) by the reaction of the esters with the appropriate dialkylaluminum alkylthiolate according to Equation 8.
Equation 8 ##STR64##
The intermediate aluminum thiolates can be prepared according to R. P. Hatch and S. W. Weinreb, Journal of Organic Chemistry, Vol. 42, 3960 (1977). The reaction of the thiolate with the ester of this invention is best carried out in a neutral solvent such as toluene or xylene at reflux for one to three hours. Best results are obtained when the aluminum thiolate compound is present in excess of the stoichiometric amount required.
Sulfonamides of formula IIb are also converted from carboxylic acid esters to the thiolesters as shown in Equation 8A according to the method of R. P. Hatch and S. W. Weinreb as described for Equation 8 wherein R, R.sub.2, R.sub.3 and R.sub.4 are as previously defined. ##STR65## The conditions described for Equation 8 are suitable for the conversion of the sulfonamides of formula IIb as shown in Equation 8A.
The product of Equation 8A are especially useful for the preparation of compounds of formula Ia, wherein Y has a substituent (CO.sub.2 C.sub.1 -C.sub.6) by the route described for Equation 3A.
An alternate route to prepare compounds where R is bonded to Q (Q.dbd.O) at a secondary carbon involves the reaction of the appropriate dialkylaluminum alcoholate and an ester of this invention wherein R is a lower primary alkyl group, preferably methyl, according to Equation 9.
Equation 9 ##STR66##
The reaction is carried out in a neutral solvent such as toluene with a boiling point sufficiently high to bring about the desired reaction during reflux. The dialkylaluminum alcoholate being present in greater than an equivalent amount to the ester for best yields. After refluxing for 1-15 hours, the reaction mixture is decomposed with dilute hydrochloric acid and the product extracted into methylene chloride. Evaporation of the methylene chloride yields the desired compound sufficiently pure for the purposes of this invention. The product can be triturated with a solvent, e.g. 1-chlorobutane to remove impurities.

A stirred mixture containing 157 g of methyl 2-sulfamoylbenzoate, 73 g of butyl isocyanate 0.3 g of 1,4-diazabicyclo[2,2,2]octane and 1.0 l of xylene was heated to reflux for one half hour. Phosgene gas was then passed into the system under a dry ice reflux condenser allowing the reaction temperature to drop to 120.degree.. This addition was continued until the reflux temperature remained at 120.degree. without further phosgene addition. The temperature of the reaction mixture was then raised to 136.degree. (by removal of the dry ice reflux condenser) after which it was cooled to room temperature and filtered. Evaporation of the filtrate yielded the desired crude sulfonyl isocyanate which could be purified by distillation at 132.degree.-138.degree. C. under 1.0 to 1.1 mm of mercury pressure. The product is extremely reactive with water so contact with moisture should be scrupulously avoided.

An infrared spectrum of the reaction mixture indicated formation of the desired sulfonylisocyanate (2250 cm.sup.-1). The resulting cloudy solution was cooled to room temperature and decanted from a small amount of solid impurity. Evaporation of the resulting clear solution yielded the desired crude sulfonyl isocyanate, which was used in subsequent steps without further purification.

The resultant residue was stirred in 25 ml of water, the pH adjusted to 10 by the addition of 50% sodium hydroxide and the solution filtered. Acidification of the filtrate to pH 3 with hydrochloric acid caused precipitation of the desired product which was removed by filtration and dried to yield 0.8 g of product melting at 173.degree.-179.degree.. It showed infrared absorption peaks at 1720, 1680, 1630 and 1550 cm.sup.-1, consistent for N-[(4-methoxy-6-methylpyrimidin-2-yl)aminocarbonyl]-2-methoxycarbonylbenzenesulfonamide.

To an anhydrous suspension of 1.4 g of 2-amino-4-methoxy-6-methyl-1,3,5-triazine in 25 ml of methylene chloride was added with stirring at ambient temperature and pressure 2.4 g of 2-methoxycarbonylbenzenesulfonylisocyanate. The mixture was thereafter stirred for 16 hours and filtered. The filtrate was evaporated to dryness, the residue was triturated with butyl chloride and the product removed by filtration. The production thus obtained melted at 165.degree., and had absorption peaks in the infrared at 1550, 1600, 1680 and 1700 cm.sup.-1 and in the NMR spectrum at 2.5, 3.65, 4.0 with an aromatic multiplet at 7.2-8 ppm.
By using the procedures of Examples 8 to 13 with equivalent amounts of appropriate 2-amino-1,3,5-triazines and appropriately substituted sulfonylisocyanates or isothiocyanates, the compounds of Table II can be prepared:
EXAMPLE 14
N-[(4-methoxy-6-methyl-1,3,5-triazin-2-yl)aminocarbonyl]-2-(1-methylpentyloxycarbonyl)benzenesulfonamide
2-Hexanol (0.61 g) in 2 ml dry toluene was slowly added at room temperature to a solution of 1.5 ml (2M) trimethylaluminum diluted with 5.0 ml dry toluene under nitrogen. The mixture was stirred at room temperature for 15 minutes and 0.95 g of N-[(4-methoxy-6-methyl-1,3,5-triazin-2-yl)aminocarbonyl]-2-methoxycarbonylbenzenesulfonamide was added. The mixture was warmed under N.sub.2 to reflux temperature for 2.5 hr. cooled to room temperature and carefully quenched with 20 ml 10% HCl. The organic phase was taken up in methylene chloride, separated, washed with water, dried over magnesium sulfate, filtered and the solvent evaporated under reduced pressure to give 0.65 g of the desired compound which melted at 125.degree.-130.degree. C. The infrared spectrum exhibited characteristic absorption for the product at 3300, 1725, 1730, 1585, 1555 cm.sup.-1.
Alternatively, compounds of Tables I and II wherein the desired ester group R is a higher alkane (C.sub.5 -C.sub.12) are also prepared by the procedure of Example 14 with an equivalent amount of the appropriate dialkylaluminum alcoholate and an appropriately substituted lower alkyl ester of this invention.
EXAMPLE 15
N-[(4,6-dimethoxy-1,3,5-traizin-2-yl)aminothioxomethyl]-2-methoxycarbonylbenzenesulfonamide
A mixture of 4.2 g of methyl 2-sulfamoyl benzoate, 4.0 g of 4,6-dimethoxy-2-isothiocyanato-1,3,5-triazine and 2.7 g of anhydrous potassium carbonate in 70 ml of acetone was warmed to 40.degree. with stirring. After 2 hours a thick precipitate formed and stirring was continued for three more hours at ambient temperature. The precipitate was removed by filtration, suspended in 150 ml of water, stirred and the pH adjusted to 2 by the addition of hydrochloric acid.
The desired product was removed by filtration washed with cold water and dried to yield 4.8 g of product melting at 165.degree.-170.degree.. It showed infrared absorption peaks at 1760, 1650 and 1600 cm.sup.-1 and nuclear magnetic resonance peaks for the methoxy groups at 4.0 and 3.8 (singlets) and 8.0-8.7 (multiplet) consistent for the desired product.
Example 15 demonstrates a method whereby compounds of this invention can be prepared wherein W is S by using equivalent amounts of the appropriate isothiocyanato pyrimidine or triazine and an appropriately substituted benzenesulfonamide.

EXAMPLE 18
N-[(4,6-dimethylpyrimidin-2-yl)aminocarbonyl]-2-carboxybenzenesulfonamide
A mixture of 2.0 g of N-[(4,6-dimethylpyrimidin-2-yl)aminocarbonyl]-2-methoxycarbonylbenzenesulfonamide and 11 ml. of 50% aqueous sodium hydroxide was warmed on a steam bath with shaking; 40 ml. of water was added and heating and shaking continued during the next half hour. The resulting solution was then filtered and the filtrate acidified with hydrochloric acid to pH 2 to yield a precipitate which was isolated by filtration to yield the title compound, 0.7 g melting at 160.degree. with decomposition. The nuclear magnetic resonance spectrum showed resonance peaks for the methyl substituents on the pyrimidine ring at 2.66 ppm and the ring hydrogens at 7.2 to 8.4 ppm. The disappearance of the resonance peak at 4.0 ppm confirmed the conversion of the methyl ester to the carboxy group.
EXAMPLE 18-A
N-[(4-Methoxy-6-methylpyrimidin-2-yl)aminocarbonyl]-2-carboxybenzenesulfonamide
4.0 g of N-[(4-methoxy-6-methylpyrimidin-2-yl)-aminocarbonyl]-2-methoxycarbonylbenzenesulfonamide was dissolved in a mixture of 20 ml of absolute ethanol, 2.5 ml of water and 2.5 g of potassium hydroxide. After stirring at 25.degree. for 24 hours the mixture had become a semi-solid mass. Enough cold water was added to dissolve the solid and the solution was acidified to pH 3 with concentrated hydrochloric acid. The resultant precipitate was isolated by filtration and washed with cold water. The precipitate was dried to afford 3.7 g of the title compound, melting at 195.degree.-200.degree.. The nuclear magnetic resonance spectrum exhibited resonances for the methyl and methoxy substituents on the pyrimidine ring at 2.67 ppm and 4.20 ppm respectively.
Peaks for the pyrimidine ring proton and phenyl ring protons were observed at 6.73 ppm and 79 to 8.6 ppm respectively. The disappearance of the resonance peak at 4.10 confirmed the conversion of the methyl ester to the carboxy group.
By using an appropriate N-[(triazinyl)aminocarbonyl]-2-alkoxycarbonylbenzenesulfonamide or a N-[(pyrimidinyl)aminocarbonyl]-2-alkoxycarbonylbenzenesulfonamide or their aminothioxomethyl analogs (W=S), the compounds of Formula I set forth in Table VII-a-VII-d can be prepared by the procedure of Example 18 or 18-A.

Methyl 2-(isocyanatosulfonyl)benzoate (10.1 g) and 8.0 g of ethyl 2-[(4-amino-6-methyl-1,3,5-triazin-2-yl)-oxy]propanoate were stirred in 80 ml of methylene chloride at ambient temperature for 18 hours. An additional 2 g of the sulfonylisocyanate was added and the reaction mixture was stirred for four more hours and then 2 g more of the sulfonylisocyanate was added. After stirring for four more hours at ambient temperature, 400 ml of water was added and the pH of this mixture was adjusted to pH 8 by the addition of 10% aqueous sodium hydroxide. The aqueous phase was separated and acidified to pH 1 with hydrochloric acid to precipitate a thick white gum. Sufficient 50% aqueous sodium hydroxide was added to achieve pH 12 and the mixture was heated on a steam bath until a clear solution resulted. The solution was again acidified with hydrochloric acid to pH 3 and the resultant cloudy solution was extracted with dichloromethane. The organic phase was dried and the solvent was removed to afford 3.7 g of the title compound as a glass.

EXAMPLE 21
N-[(4-methoxy-6-methyltriazin-2-yl)aminocarbonyl]-2-(methylthio)-carbonylbenzenesulfonamide
Trimethylaluminum (6.0 ml, 2M) was charged via syringe to 15 ml dry toluene under nitrogen atmosphere and 3.8 g N-[(4-methoxy-6-methyltriazin-2-yl)aminocarbonyl]-2-methoxycarbonyl-benzenesulfonamide was added portionwise. After stirring at room temperature for one hour, methyl mercaptan (gas) was passed through the reaction mixture until the initial temperature rise subsided, whereupon the addition was discontinued. The reaction mixture was allowed to stir at room temperature for 1 hour, and quenched with 25 ml of 10% HCl. The resultant white suspension was filtered to give 2.9 g white solid which showed infrared absorption peaks at 1740, 1690 cm.sup.-1, consistent for N-[(4-methoxy-6-methyltriazin-2-yl)aminocarbonyl]-2-(methylthio)carbonylbenzenesulfonamide.
EXAMPLE 22
N[(4-methoxy-6-methylpyrimidin-2-yl)aminocarbonyl]-2-(n-butylthio)carbonylbenzenesulfonamide
Trimethylaluminum (1.5 ml) (2M) was charged via syringe to 5.0 ml dry toluene under nitrogen atmosphere and 0.54 g (0.006 mole) N-butanethiol in 2.0 ml toluene was added dropwise. N-[(4-methoxy-6-methylpyrimidin-2-yl)aminocarbonyl]-2-methoxycarbonylbenzenesulfonamide (0.95 g) was added portionwise and the mixture warmed to 80.degree. C. for 3 hr. After cooling to room temperature, the mixture was quenched with 25 ml of 10% HCl. Methylene chloride was added, separated, dried over magnesium sulfate, filtered and evaporated to give a crude oil. Trituration with hexanes gave 0.6 g white solid, m.p. 115.degree.-120.degree. C., showing infrared absorption peaks at 1725, 1680, 1600, 1560 cm.sup.-1 consistent for N-[(4-methoxy-6-methylpyrimidin-2-yl)aminocarbonyl]-2-(N-butylthio)carbonylbenzenesulfonamide.
EXAMPLE 23
N-[(4-Methoxy-6-methyl-1,3,5-triazin-2-yl)aminocarbonyl]-2-isopropylthiocarbonylbenzenesulfonamide
To 1.5 ml (2N) trimethylaluminum in 5 ml dry toluene under N.sub.2 was added dropwise 0.48 g (6.0 mmole) 2-propanethiol in 2 ml toluene. The resultant aluminum reagent was stirred at room temperature for 15 minutes, and 0.95 g (2.5 mmole) N-[(4-methoxy-6-methyl-1,3,5-triazin-2-yl)aminocarbonyl]-2-methoxycarbonylbenzenesulfonamide was added in one portion. The suspension was heated to 80.degree. C. for 3 hours, cooled to room temperature and 10% HCl (15 ml) was added. The mixture was stirred until a fine solid precipitated which was filtered off, washed with hexanes and air dired to yield 0.4 g of product melting at 155.degree.-158.degree. C. It showed infrared absorption peaks consistent for N-[(4-methoxy-6-methyl-1,3,5-triazin-2-yl)aminocarbonyl]-2-isopropylthiocarbonylbenzenesulfonamide.
By using the procedures of Examples 21-23 with equivalent amounts of an appropriately substituted dialkyl-aluminum alkylthiolate and appropriately substituted esters of this invention, the compounds of Table IX can be prepared.

Formulations
Useful formulations of the compounds of Formula I can be prepared in conventional ways. They include dusts, granules, pellets, suspensions, emulsions, wettable powders, emulsifiable concentrates and the like. Many of them can be applied directly. Sprayable formulations can be extended in suitable media and used at spray volumes of from a few liters to several hundred liters per hectare. The formulations, broadly, contain about 0.1% to 99% by weight of active ingredient(s) and at least one of (a) about 0.1% to 20% surfactant(s) and (b) about 1% to 99.9% solid or liquid diluent(s). More specifically, they will contain these ingredients in the approximate proportions set forth in Table X.
TABLE X______________________________________ Weight Percent* Active Surfac- Ingredient Diluent(s) tant(s)______________________________________Wettable Powders 20-90 0-74 1-10Oil Suspensions, 3-50 40-95 0-15Emulsions (includingEmulsifiable Concentrates)Aqueous Suspensions 10-50 40-84 1-20Dusts 1-25 70-99 0-5Granules and Pellets 0.1-95 5-99.9 0-15______________________________________ *Active Ingredient plus at least one of a Surfactant or a Diluent equals 100 weight percent.
Lower or higher levels of active ingredient can, of course, by present depending on the intended use and the physical properties of the compound. Higher ratios of surfactant to active ingredient are sometimes desirable, and are achieved by incorporation into the formulation, or by tank mixing.
Some typical solid diluents are described in Watkins, et al., "Handbook of Insecticide Dust Diluents and Carriers", 2nd Ed., Dorland Books, Caldwell, N.J., but other solids, either mined or manufactured, may be used. The more absorptive diluents are preferred for wettable powders and the denser ones for dusts. Typical liquid diluents and solvents are described in Marsden, "Solvents Guide", 2nd Ed., Interscience, New York, 1950. Solubility under 0.1% is preferred for suspension concentrates, solution concentrates are preferably stable against phase separation at 0.degree. C. "McCutcheon's Detergents and Emulsifiers Annual", MC Publishing Corp., Ridgewood, N.J., as well as Sisely and Wood, "Enclopedia of Surface Active Agents", Chemical Publishing Co., Inc., New York, 1964, list surfactants and recommended uses. All formulations can contain minor amounts of additives to reduce foaming, caking, corrosion, microbiological growth, etc.
The methods of making such compositions are well known. Solutions are prepared by simply mixing the ingredients. Fine solid compositions are made by blending, and usually, grinding as in a hammer or fluid energy mill. Suspensions are prepared by wet milling (see, for example, Littler, U.S. Pat. No. 3,060,084). Granules and pellets may be made by spraying the active material on preformed granular carriers or by agglomeration techniques. See J. E. Browning, "Agglomeration", Chemical Engineering, Dec. 4, 1967, pp. 147ff. and "Perry's Chemical Engineer's Handbook", 4th Ed., McGraw-Hill, New York, 1963, pp. 8-59ff.

UTILITY
The compounds of the present invention are highly active herbicides. They have utility for broad-spectrum pre- and/or post-emergence weed control in areas where complete control of all vegetation is desired, such as around fuel storage tanks, ammunition depots, industrial storage areas, oil well sites, drive-in theatres, around billboards, highway and railroad structures. By properly selecting rate and time of application, compounds of this invention may be used also to modify plant growth beneficially and for the selective control of weeds in crops such as wheat and barley.
The precise amount of the compound of Formula I to be used in any given situation will vary according to the particular end result desired, the amount of foliage present, the weeks to be controlled, the crop species, the soil type, the formulation and mode of application, weather conditions, etc. Since so many variables play a role, it is not possible to state a rate of application suitable for all situations. Broadly speaking, the compounds of this invention are used at levels of about 0.005 to 20 kg/ha with a preferred range of 0.125 to 10 kg/ha. In general, the higher rates of application from within this range will be selected for adverse conditions or where extended persistence in soil is desired and the lower rates for selective weed control in crops.
The activity of these compounds was discovered in a number of greenhouse and field tests. The tests are described and the data resulting from them are shown below. The ratings are based on a numerical scale extending from 0=no effect, to 10=maximum effect. The accompanying descriptive symbols have the following meanings:
C=chlorosis or necrosis
D=defoliation
E=emergence inhibition
G=growth retardation
H=formative effects
U=unusual pigmentation
6Y=abscised buds or flowers
TEST A
Seeds of crabgrass (Digitaria spp.), barnyardgrass (Echinochloa crusgalli), wild oats (Avena fatua), cassia (Cassia tora), morningglory (Ipomoea spp.), cocklebur (Xanthium spp.), sorghum, corn, soybean, rice, wheat and nutsedge tubers (Cyperus rotundus) were planted in a growth medium and treated preemergence with a nonphytotoxic solvent solution of the compounds of Table XII. Other batches of seeds and tubers for all of the foregoing weed and crop plants were planted at the same time as controls. The control plantings were untreated; i.e., neither any compound nor any solvent was applied. At the same time, cotton having five leaves (including cotyledonary ones), bush beans with the third trifoliate leaf expanding, crabgrass with two leaves, barnyardgrass with two leaves, wild oats with two leaves, cassia with three leaves (including cotyledonary ones), morningglory with four leaves (including the cotyledonary ones), cocklebur with four leaves (including the cotyledonary ones), sorghum with four leaves, corn with four leaves, soybean with two cotyledonary leaves, rice with three leaves, wheat with one leaf, and nutsedge with three-five leaves were sprayed with a nonphytotoxic solvent solution of the compounds of Table XII. Other groups of all the same weed and crop plants were sprayed with the same nonphytotoxic solvent so as to provide control plants. Preemergence and postemergence treated plants and controls were maintained in a greenhouse for sixteen days, then all treated plants were compared with their respective controls and rated visually for response to treatment. The data in Table XII shows that the compounds of this invention are very effective as herbicides.

TEST B
Two bulb pans were filled with fertilized and limed Fallsington silt loam soil. One pan was planted with seeds of corn, sorghum, Kentucky bluegrass and several grassy weeds. The other pan was planted with seeds of soybeans, purple nutsedge tubers (Cyperus rotundus), and seeds of several broadleaf weeds. Seeds of the following grassy and broadleaf weeds were planted: crabgrass (Digitaria sanguinalis), barnyardgrass (Echinochloa crusgalli), wild oats (Avena fatua), johnsongrass (Sorghum halepense), giant foxtail (Setaria faberii), dallisgrass (Paspalum dilatatum), cheatgrass (Bromus secalinus), mustard (Brassica arvensis), cocklebur (Xanthium pennsylvanicum), pigweed (Amaranthus retroflexus), morningglory (Ipomoea hederacea), cassia (Cassia tora), teaweed (Sida spinosa), velvetleaf (Abutilon theophrasti), and jimsonweed (Datura stramonium). A smaller pot was also filled with prepared soil and planted with rice and wheat seeds. Another small pot was planted with seeds of sugarbeets. The above four containers were treated preemergence with nonphytotoxic solvent solutions of the compounds of this invention (i.e., solutions of said compound were sprayed on the soil surface before seed germination). Duplicates of the above-described seeded containers were prepared without treatment and used as controls.
Twenty-eight days after treatment, the treated and control plants were evaluated and the data recorded as set forth in Table XIII.

Pots filled with Fallsington silt loam were planted to soybeans, cotton, corn, rice, wheat, sorghum, alfalfa, velvetleaf (Abutulon theophrasti), sesbania (Sesbania exaltata), cassia (Cassia tora), morningglory (Ipomoea spp.), jimsonweed (Datura stramonium), cocklebur (Xanthium pennsylvanicum), crabgrass (Digitaria spp.), nutsedge (Cyperus rotunda), barnyardgrass (Echinochloa crusgalli), giant foxtail (Setaria faberii), and wild oats (Avena fatua). Approximately 21/2 weeks after planting, the young plants and the soil around them were sprayed overall with the compound of Example 1 dissolved in a nonphytotoxic solvent. Other groups of all the same weed and crop plants were sprayed with the same nonphytotoxic solvent so as to provide control plants. Fourteen days after treatment, all treated plants were compared with the nonphytotoxic solvent controls and visually rated for response to treatment to give the data presented in Table XIV. It will be noted that wheat shows tolerance for several of the compounds included in this table.

TEST D
The high herbicidal activity of one of the compounds from within the scope of the invention is evident from the results obtained in this test. The experiment concerned pre-emergence applications on soil. The containers used were 25 cm diameter plastic pots filled with Fallsington silt loam. One set of pots was planted to weeds the seeds of which were uniformly mixed with the top 1.2 cm layer of soil. The species selected were: johnsongrass (Sorghum halepense), barnyardgrass (Echinochloa crusgalli), crabgrass (Digitaria sanguinalis), giant foxtail (Setaria faberii), velvetleaf (Abutilon theophrasti), jimsonweed (Datura stramonium), mustard (Brassica arvensis) and pigweed (Amaranthus retroflexus). Another set of pots was planted to the following crops with from one to four species per pot: corn (planting depth 3.7 cm), cotton, soybeans, sunflower, Clinton oats, wheat, Black Valentine beans, rice, sorghum, peas, flax and peanuts (all at 2.5 cm depth), cucumbers, cabbage, alfalfa, safflower, sugarbeets, tomato, spinach, barley and Kentucky bluegrass (all at 1.2 cm depth). Immediately after planting, the test chemical was applied to the soil surfaces dissolved in a non-phytotoxic solvent. One pot from the weed phase and one of each of the crop species were left untreated for the purpose of comparison. The treated and untreated pots were promptly watered with approximately 4 mm of simulated rainfall and then held in a greenhouse for several weeds. Visual weed and crop response ratings were made 28 days after treatment utilizing the rating system as described above the test procedure A. The data are given in Table XV.

TEST E
This greenhouse test demonstrates the utility of certain compounds from within the scope of the invention for the pre- and post-emergence control of broadleaved weeds and nutsedge in young wheat and barley plantings. The containers used were 25 cm diameter plastic pots filled with fertilized and limed Fallsington silt loam. Plantings of the following weed species were made twice, at a 10-day interval: mustard (Brassica arvensis), cocklebur (Xanthium spp.), morningglory (Ipomoea hederacea), cassia (Cassia tora), velvetleaf (Abutilon theophrasti), alfalfa (used as an indicator species), kochia (Kochia scoparia), sesbania (Sesbania exaltata), Russian thistle (Salsola kali), jimsonweed (Datura stramonium), and nutsedge (Cyperus rotundus). In addition, wheat and barley were planted in separate 15 cm diameter plastic pots filled with the same soil at the time of the early planting only. All plantings were treated with the test chemicals dissolved in a non-phytotoxic solvent immediately following completion of the second planting operation. At this time, the wheat was around 15-17.5 cm tall and the barley 12.5 to 15 cm tall, both in the 2-leaf stage of growth. The weed species of the earliest planting date were from 2.5 to 12.5 cm tall. The rates of application selected were 0.004, 0.007, 0.015 and 0.030 kg/ha for the weed phase and 0.12, 0.25 and 0.50 kg/ha for wheat and barley. The post-emergence part of this test was visually rated for plant response 21 days after treatment, and the pre-emergence part 28 days after treatment. The rating system used was as described for test procedure A. The data are summarized in Table XVI.

TEST F
Several compounds from within the scope of the invention are highly active against nutsedge, as evident from the following test.
Purple nutsedge tubers (Cyperus rotundus) were planted about 2 cm deep in Fallsington silt loam contained in plastic pots 10 cm in diameter. Five tubers were put in each pot. Compounds of this invention were sprayed dissolved in a non-phytotoxic solvent at a volume rate of 560 l/ha. in four different methods of treatment, i.e., soil surface spray, tuber/soil spray, soil incorporated and post-emergence. For the soil surface spray, the compounds were sprayed on the firmed soil surface immediately after planting. For the tuber/soil spray, the compounds were sprayed on the exposed tubers and subtending soil before the untreated covering soil was added. Soil incorporation treatments were mixed in the covering soil. Post-emergence treatments were sprayed on the nutsedge foliage and surrounding soil surface after the nutsedge had emerged and had reached the height of about 12 cm.
Immediately after spraying the surface spray, tuber/soil spray and soil incorporated treatments were misted with about 0.3 cm of water over a 90 minute period and then placed in the greenhouse. Post-emergence treatments were placed directly into the greenhouse and watered carefully so that treatments would not be washed from the foliage.
The following Table XVII gives results 4 weeks after treating nutsedge with compounds of this invention.

TEST G
Purple nutsedge tubers (Cyperus rotundus, L.) were planted about 2 cm deep in Fallsington silt loam (about 1% organic matter from Delaware) and in Flanagan loam (about 4% organic matter) from Illinois. Five tubers were planted in each 10 cm diameter plastic pot. Treatments recorded in Table XVII were applied in three different ways, i.e., soil surface spray, tuber/soil spray and soil incorporated. In surface sprays, the material was sprayed on the firmed soil surface after planting, but before nutsedge emergence. In tuber/soil sprays, the material was sprayed on exposed tubers and subtending soil before the tubers were covered with untreated soil. Soil incorporated treatments were mixed in the covering soil.
Immediately after treating, the treated pots were misted with about 0.3 cm of water over a 90 minute period and placed in the greenhouse. The high degree of activity of these compounds on nutsedge is demonstrated by the ratings after 4 weeks as recorded in Table XVIII.

Two ten-inch in diameter plastic pans lined with polyethylene liners were filled with prepared Fallsington silt loam soil. One pan was planted with seeds of wheat (Triticum aestivum), barley (Hordeum vulgare), wild oats (Avena fatua), downy brome (Bromus tectorum), cheatgrass (Bromus secalinus), blackgrass (Alopecurus myosuroides), annual bluegrass (Poa annua), green foxtail (Setaria viridis), quackgrass (Agropyron repens), Italian ryegrass (Lolium multiflorum) and ripgut brome (Bromus rigidus). The other pan was planted with seeds of wild buckwheat (Polygonum convolvulus), Kochia scoparia, smartweed (Polygonum pennsylvanicum), false chamomile (Matricaria inodora), jimhill mustard (Sisymbrium altissium), wild mustard (Brassica kaber), tansy mustard (Descurainia pinnata), pigweed (Amaranthus retroflexus) and Russian thistle (Salsola kali). The above two pans were treated pre-emergence. At the same time two pans in which the above plant species were growing were treated post-emergence. Plant height at the time of treatment ranged from 1-15 cm depending on plant species.
The compounds applied were diluted with a non-phytotoxic solvent and sprayed over-the-top of the pans. As untreated control and a solvent alone control were included for comparison. All treatments were maintained in the greenhouse for 20 days at which time the treatments were compared to the controls and the effects visually rated. The recorded data are presented in Table XIX. Here again, the potential utility of certain test compounds for weed control in wheat and barley is evident.

TEST I
Five-inch in diameter plastic pots were filled with a 50-50 mixture of Fallsington silt loam soil and sand and seeds of the following planted (one plant species per pot): milkweed vine (Morrenia odorata), plantain (Plantago spp.), burdock (Arctium minus), field bindweed (Convolvulus arvensis), dandelion (Taraxacum officinale), horsenettle (Solanum carolinense), bermudagrass (Cynodon dactylon), quackgrass (Agropyron repens), dallisgrass (Paspalum dilatatum) and johnsongrass (Sorghum halepense). The pots were placed in the greenhouse and the plants grown for several weeks.
The compound evaluated was diluted with a non-phytotoxic solvent and sprayed on the plant foliage. Untreated and solvent controls were included for comparison. One and eight weeks after treatment, a visual rating of the compound's effects on plant growth were made. These ratings are presented in Table XX. The data indicate the high activity of the test compound for the control of established broadleaved and grass perennial weeds.

TEST J
The high herbicidal activity of one of the compounds from within the scope of the invention was confirmed in a field test. The material was applied pre-emergence to a silt loam. Three days after treatment the area was irrigated with 2.5 cm of water. Four weeks later, the percentage of control was estimated for each species, as shown in Table XXI.

TEST K
The response of a number of noxious weed species to post-emergence applications of the same compound as used in Test J was studied in another field test. At the time of treatment, one month after mowing, the mixed vegetation was approximately 15 cm tall. The chemical was applied in water containing 0.2% of Surfactant WK.RTM. at an overall volume of 500 l/ha. Each treatment was replicated three times. Approximately 5 cm of rainfall was recorded 4 days after treatment and an additional 37 cm fell before weed control ratings were made 16 weeks after treatment. The figures are presented in Table XXII.
