The presence of undesired vegetation causes substantial damage to useful crops, especially agricultural products that satisfy man's basic food needs, such as soybeans, wheat and the like. The current population explosion and concomitant world food shortage demand improvements in the efficiency of producing these crops. Prevention or minimizing the 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 exists, however, for still more effective herbicides that destroy or retard weeds without causing significant damage to useful crops.

R.sub.1 is ##STR31## where R.sub.d is ##STR32## where n is 0 or 2;
R.sub.1 ' is H, Cl, F, Br, CH.sub.3 or OCH.sub.3 ;
R.sub.2 is C.sub.1 -C.sub.6 alkyl, C.sub.3 -C.sub.4 alkenyl, C.sub.3 -C.sub.6 cycloalkyl, C.sub.5 -C.sub.6 cycloalkenyl, C.sub.4 -C.sub.7 cycloalkylalkyl, C.sub.3 -C.sub.6 cycloalkyl substituted with 1-2 CH.sub.3 groups, C.sub.3 -C.sub.5 alkynyl, C(CH.sub.3).sub.2 CN, (CH.sub.2).sub.m CN, where m is 1 or 2, CF.sub.2 CF.sub.2 H, CF.sub.2 CHFCl, CF.sub.2 CHFBr, CF.sub.2 CHFCF.sub.3, CH.sub.2 CF.sub.3, CH.sub.2 CH.sub.2 OCH.sub.3, CH.sub.2 CH(CH.sub.3)OCH.sub.3, (CH.sub.2).sub.3 OCH.sub.3, or OCH.sub.3, provided that when R.sub.2 is OCH.sub.3, R.sub.3 is CH.sub.3, CH(R.sub.7)CO.sub.2 R.sub.8 or CH(R.sub.7)CON(R.sub.8).sub.2, where R.sub.7 is H or CH.sub.3, and R.sub.8 is C.sub.1 -C.sub.3 alkyl; or R.sub.2 is ##STR33## where
R.sub.9 is H, CH.sub.3, Cl, Br or F;
R.sub.3 is C.sub.1 -C.sub.4 alkyl, C.sub.3 -C.sub.4 alkenyl, CH.sub.2 CH.sub.2 OCH.sub.3, CH.sub.2 CH(CH.sub.3)OCH.sub.3, (CH.sub.2).sub.m CN, where m is 1 or 2, CH(R.sub.7)CO.sub.2 R.sub.8, --CH.sub.2 CF.sub.3, or NR.sub.2 R.sub.3 taken together are ##STR34## provided that when R.sub.2 is CF.sub.2 CHFCl, CF.sub.2 CHFBr, CF.sub.2 CF.sub.2 H, or CF.sub.2 CHFCF.sub.3, then R.sub.3 is C.sub.1-4 alkyl; Also provided that when R.sub.1 is CN or N.dbd.C.dbd.O, it cannot be in the 3-position.
The above reaction is carried out by heating a mixture of the appropriate sulfonamide (II), an alkyl isocyanate such as butyl isocyanate and a catalytic amount of a tertiary amine such as 1,4-diaza[2,2,2]bicyclooctane (DABCO) in xylene, or other inert solvent of boiling point .gtoreq.135.degree. to approximately 135.degree.. Phosgene is then added to the mixture over a 1-6 hour period until an excess of phosgene is present as indicated by a drop in the boiling point to less than 130.degree.. The mixture is cooled and filtered to remove a small amount of insoluble by-products. The solvent and the alkyl isocyanate are distilled off in-vacuo leaving a residue of the crude, sulfonyl isocyanate; IIa, which can be used without further purification.
The preparation of the sulfonamides, II, is described in Equation 8.
The sulfonyl isocyanates, IIa, can also be prepared, as shown in Equation 2, by first preparing the n-butylsulfonylureas III; and, reacting the compounds III with phosgene. ##STR35## wherein A, R.sub.1, R.sub.1 ', R.sub.2 and R.sub.3 are as defined in Equation 1.
The compounds III are conveniently prepared by stirring a mixture of the sulfonamides, II, anhydrous potassium carbonate, and n-butyl isocyanate in acetone or methyl ethyl ketone at 25.degree.-80.degree. until all of the isocyanate has reacted. The products are isolated by quenching in dilute mineral acid or by distilling off the solvent and recrystallizing the residue. The compounds III are treated with phosgene and a catalytic amount of DABCO in refluxing xylene or chlorobenzene in a manner analogous to that described in Equation 1.
Where W=S in Formula 1, the useful isothiocyanate intermediates, IV, are prepared according to Equation 3. ##STR36## wherein A, R.sub.1, R.sub.1 ', R.sub.2 and R.sub.3 are as defined in Equation 1.
The substituted sulfonamide is dissolved in dimethylformamide (DMF) with an equivalent amount of carbon disulfide, and two equivalents of potassium hydroxide are added in portions at room temperature. The mixture is stirred for 1-8 hours then diluted with ethyl acetate, ethyl ether, or other similar aprotic solvent to precipitate the dipotassium salt of the dithiocarbamic acid. The salt is isolated and suspended in an inert solvent such as xylene, chloroform, or carbon tetrachloride. Phosgene is added below room temperature and the mixture stirred at room temperature for 1-3 hours. The sulfonylisothiocyanate is isolated by filtering off the precipitated potassium chloride and concentrating the filtrate. These compounds tend to dimerize on standing and therefore should be used soon after preparation.
Compounds of Formula I can be prepared by the reaction described in Equation 4. ##STR37## wherein
A, R.sub.1, R.sub.1 ', R.sub.2 and R.sub.3 are as defined in Equation 1;
W is oxygen or sulfur;
R.sub.5 is H or methyl;
R.sub.6 is ##STR38## and
X is H, CH.sub.3, CH.sub.3 O or CH.sub.3 CH.sub.2 O;

X.sub.1 is H, OCH.sub.3 or CH.sub.3 ;
Y.sub.1 is H, OCH.sub.3, OCH.sub.2 CH.sub.3 or CH.sub.3, provided that
X.sub.1 and Y.sub.1 are not both H simultaneously; and
Z is N or CH.
The reaction of Equation 4 is best carried out in inert aprotic solvent such as methylene chloride, tetrahydrofuran, acetonitrile at a temperature between 20.degree. and 80.degree.. A catalytic amount of DABCO may be used to accelerate the reaction. In the cases in which the products are insoluble in the reaction solvent, they may be isolated by simple filtration. When the products are soluble in the reaction solvent they are isolated by evaporation of the solvent and trituration of the residue with solvents such as 1-chlorobutane ethylether, or methanol and filtration.
Compounds of Formula 1 in which W=S and R.sub.5 =H can also be prepared by the reaction shown in Equation 5. ##STR40## wherein A, R.sub.1, R.sub.1 ', R.sub.2, R.sub.3 and R.sub.6 are as defined in Equations 1-4, and R.sub.4 is H or CH.sub.3.
The reaction of Equation 5 is best carried out by suspending the sulfonamide, the isothiocyanate and an equivalent of a base such as anhydrous potassium carbonate in a solvent such as acetone, methyl ethyl ketone, acetonitrile or ethyl acetate. The reaction is stirred at 25.degree.-80.degree. for 1 to 24 hours. In some cases, the product precipitates from the reaction mixture and can be filtered off, suspended in dilute mineral acid, filtered again and washed with cold water. If the product does not precipitate, 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, VI, which are used in the procedure of Equation 5 are prepared according to the method of Japan Patent Application Pub. Kokai No. 51-143686, June 5, 1976; or that of W. Abraham and G. Barnikow, Tetrahedron 29, 691-7 (1973) both of which are herein incorporated by reference.
Compounds of Formula 1 in which W=S and R.sub.4 =H can also be prepared by the procedure shown in Equation 6. ##STR41## wherein A, R.sub.1 ', R.sub.1 -R.sub.6 are as defined in Equations 1-5.
In the procedure of Equation 6, the aminotriazine or aminopyrimidine is added to a suspension of sodium hydride in dimethylformamide (DMF) or tetrahydrofuran (THF) and allowed to stir at room temperature for 1-4 hours. The resulting salt solution or suspension is then added to a solution of the sulfonyl isothiocyanate in DMF or THF and allowed to stir at room temperature for 1-4 hours. The product is isolated by quenching the reaction mixture in excess dilute mineral acid and filtering off the insoluble product; or by first evaporating the solvent off and triturating the residue in dilute mineral acid and collecting the solid product.
Alternatively, compounds of Formula I in which R.sub.4 is a methyl group may be prepared by the procedure shown in Equation 7. ##STR42## wherein A, R.sub.1 ', R.sub.1 -R.sub.6 and W are as defined in Equations 1-6.
The reaction of Equation 7 can best be carried out by adding an equivalent of an acid acceptor, such as triethylamine, pyridine, or potassium carbonate, to a mixture of the chloride VII, and the aminoheterocyclic, Va, in an inert organic solvent such as tetrahydrofuran, methylene chloride or acetonitrile. Temperatures of 20.degree.-80.degree. may be employed. 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 VII can be prepared by phosgenation or thiophosgenation of the N-methylsulfonamide salts. The sulfonamide salt is added to an excess of phosgene or thiophosgene in an inert organic solvent, such as tetrahydrofuran or methylene chloride. After removal of the excess phosgene, the chloride VII can be isolated or reacted in-situ with the aminoheterocycle Va.
2-Aminopyrimidines are described by D. J. Brown in "The Pyrimidines", Vol. XVI of "The Chemistry of Heterocyclic Compounds", Interscience, New York, and London. The 2-amino-1,3,5-triazines are reviewed by K. R. Huffman, in "The Triazines" of this same series. The synthesis of triazines is also described in U.S. Pat. No. 3,154,547, and by H. R. Huffman and F. C. Schaeffer, J. Org. Chem. 28, 1816-1821 (1963). All of the above are herein incorporated by reference.
The benzenesulfonamides of Formula II; which are the starting materials in Equations 1, 2 and 3, can be prepared by the four step procedure described in Equation 8. ##STR43## wherein A, R.sub.1 ', R.sub.1, R.sub.2, and R.sub.3 are as defined in Equations 1-7, with the exception that R.sub.1 cannot be NO.sub.2.
In step 8a, the o-nitrobenzenesulfonyl chloride in Formula VIII, which are well-known in the art, are treated with an amine or an alcohol of Formula VIIIa in an inert organic solvent such as methylene chloride, ethyl ether, or tetrahydrofuran at 0.degree.-50.degree.. When VIIIa is an amine, it may be taken in excess to act as an acid acceptor; or, alternatively, a tertiary amine such as triethylamine or pyrimidine may be used as an acid acceptor. When VIIIa is an alcohol, a tertiary amine such as triethylamine or pyridine must be used as an acid acceptor. The by-product amine hydrochloride is filtered off or washed out of the solvent with water and the product isolated by evaporation of the solvent.
The reduction described in step 8b is accomplished by treating a solution of the compounds of Formula IX, in a solvent such as ethanol, ethyl acetate, or DMF, in a pressure vessel, with 100-1000 pounds per square inch of hydrogen at 80.degree.-150.degree. in the presence of a hydrogenation catalyst such as 5-10% palladium absorbed on carbon. When the theoretical amount of hydrogen has been absorbed, the solution is cooled and the catalyst is removed by filtration. The product is then isolated by evaporation of the solvent.
In the case where R.sub.1 =NO.sub.2, the reduction of step 8b can be accomplished using ammonium sulfide or sodium hydrosulfide instead of catalytic hydrogenation. This type of procedure is described in Organic Synthesis Coll. Vol. III, pgs. 242-3, John Wiley and Sons, Inc., New York and London (1955), the disclosure of which is herein incorporated by reference.
The diazotization and coupling with sulfur dioxide, described in step 8c, is accomplished in the following manner. A solution of the aniline of Formula X in a mixture of concentrated hydrochloric acid and glacial acetic acid is treated with a solution of sodium nitrite in water at -5.degree. to 0.degree.. After stirring for 10-15 minutes at 0.degree. to insure complete diazotization, this solution is added to a mixture of an excess of sulfur dioxide, and a catalytic amount of cuprous chloride in glacial acetic acid at 0.degree.-5.degree.. The temperature is kept at 0.degree.-5.degree. for 1/4 to 1 hour then raised to 20.degree.-25.degree. and held at that temperature for 2-4 hours. This solution is then poured into a large excess of ice water. The sulfonyl chloride products, XI, can be isolated by filtration or by extraction into a solvent such as ethyl ether or methylene chloride followed by evaporation of the solvent.
The amination described in step 8d is conveniently carried out by treating a solution of the sulfonyl chloride of Formula XI with an excess of anhydrous ammonia in a solvent such as ethyl ether or methylene chloride at 0.degree.-25.degree.. If the product sulfonamide, II, is insoluble it may be isolated by filtration followed by washing out the salts with water. If the product sulfonamide is soluble in the reaction solution, it may be isolated by filtering off the precipitated ammonium chloride and evaporation of the solvent.
Compounds of Formula 1 in which R.sub.1 =NH.sub.2 can be prepared by the reaction shown in Equation 9. ##STR44## wherein A, R.sub.1 ', R.sub.2 -R.sub.6 and W are as defined in Equations 1-8.
The reduction described in Equation 9 is accomplished by treating a solution of the compounds of Formula XII in a solvent such as ethyl acetate or DMF in a pressure vessel, with 100-1000 pounds per square inch of hydrogen at 80.degree.-150.degree. in the presence of a suitable hydrogenation catalyst such as 5-10% palladium absorbed on carbon. When the theoretical amount of hydrogen has been absorbed, the solution is cooled and the catalyst is removed by filtration. The product is then isolated by evaporation of the solvent.
Compounds of Formula I can also be prepared by the method described in Equation 10. ##STR45## wherein A, R.sub.1, and R.sub.1.sup.' are as described in Equation 1;

Reaction Step (10a)
In Reaction Step (10a), an aromatic sulfonamide of Formula II is contacted with a heterocyclic isocyanate of Formula XIII to yield an N-(haloheterocyclicaminocarbonyl)aromatic sulfonamide of Formula XIV.
The heterocyclic isocyanates used in Reaction (10a) may be prepared according to methods described in Swiss Pat. No. 579,062, U.S. Pat. No. 3,919,228, U.S. Pat. No. 3,732,223 and Angew Chem. Int. Ed. 10, 402 (1976), the disclosures of which are herein incorporated by reference.
The aromatic sulfonamide and the heterocyclic isocyanate are contacted in the presence of an inert organic solvent, for example, acetonitrile, tetrahydrofuran (THF), toluene, acetone or butanone. Optionally, a catalytic amount of a base, such as 1,4-diazabicyclo[2.2.2]octane (DABCO), potassium carbonate, sodium hydride or potassium tert-butoxide, may be added to the reaction mixture. The quantity of base constituting a catalytic amount would be obvious to one skilled in the art. The reaction mixture is preferably maintained at a temperature of about 25.degree. to 110.degree. C., and the product can generally be recovered by cooling and filtering the reaction mixture. For reasons of efficiency and economy, the preferred solvents are acetonitrile and THF, and the preferred temperature range is about 60.degree. to 85.degree. C.
Reaction Steps (10b) and (10c)
In Reaction Steps (10b) and (10c), one or two of the halogen atoms on the heterocyclic ring of the compound of Formula XIV is displaced by a nucleophilic species. Generally, this may be done by contacting the compound of Formula XIV either with alkanol, R.sub.12 OH, or with alkoxide, --OR.sub.12, where R.sub.12 is as defined above.
Thus, in Reaction Step (10b), a compound of Formula XIV, substituted with one displaceable group, can be contacted with at least one equivalent of alkanol, R.sub.12 OH. This reaction is sluggish, however, and it is preferred to contact the compound of Formula XIV with at least two equivalents of alkoxide, --OR.sub.12. The alkoxide can be provided in a number of ways:
(a) The compound of Formula XIV can be suspended or dissolved in an alkanol solvent, R.sub.12 OH, in the presence of at least two equivalents of alkoxide, --OR.sub.12. The alkoxide can be added directly as alkali metal or alkaline earth metal alkoxide or can be generated by the addition to the alkanol solvent of at least two equivalents of a base capable of generating alkoxide from the solvent. Suitable bases include, but are not limited to, the alkali and alkaline earth metals, their hydrides and tert-butoxides. For example, when R.sub.12 is methyl, the compound of Formula XIV could be suspended or dissolved in methanol in the presence of two equivalents of sodium methoxide. Alternatively, two equivalents of sodium hydride could be used in place of the sodium methoxide.
(b) The compound of Formula XIV can be suspended or dissolved in an inert solvent in the presence of at least two equivalents of alkoxide, --OR.sub.12. Suitable inert solvents include, but are not limited to, acetonitrile, THF and dimethylformamide. The alkoxide may be added directly as alkali metal or alkaline earth metal alkoxide or may be generated from alkanol and a base as described in (a) above. For example, when R.sub.12 is methyl, the compound of Formula XIV could be suspended or dissolved in THF in the presence of two equivalents of sodium methoxide. Alternatively, two equivalents each of methanol and sodium hydride could be used instead of sodium methoxide.
For reasons of economy and efficiency, procedure (a) is the more preferred method.
It should be noted that two equivalents of alkoxide are required for Reaction Step (10b) whereas only one equivalent of alkanol is needed for the same process. This difference is due to the reaction which is believed to occur between the alkoxide and the sulfonyl nitrogen of the sulfonamide of Formula XIV. When alkoxide is used, the first equivalent of alkoxide removes a proton from the sulfonyl nitrogen, and it is only the second equivalent which effects displacement of the halogen. As a result, two equivalents of alkoxide are required. The resulting salt must be acidified, e.g., with sulfuric, hydrochloric or acetic acid, to yield a compound of Formula XV. Applicant, of course, does not intend to be bound by the mechanism described above.
In Reaction Step (10c) a compound of Formula XVa, substituted with at least one displacement group, is contacted with either one equivalent of alkanol, R.sub.13 OH, or with two equivalents of alkoxide, --OR.sub.13 where R.sub.13 is as described above. The compound of Formula XVa is prepared according to Reaction Step (10b) from a compound of Formula XV where Y.sub.2 is Cl or Br. When alkoxide, --OR.sub.13 is used it may be provided in either of the methods described above in connection with Reaction Step (10b), and the resulting salt can be acidified to yield a compound of Formula XVI.
When R.sub.12 =R.sub.13, Reaction Steps (10b) and (10c) may be combined. Thus, a compound of Formula XIV may be contacted either with at least two equivalents of alkanol, R.sub.13 OH, or with at least three equivalents of alkoxide, --OR.sub.13.
When a compound of Formula XIV contains two displaceable groups, i.e., both X.sub.2 and Y.sub.2 are Cl or Br, certain reaction conditions will favor displacement of only one of the group. These conditions are the use of low temperatures and, when alkoxide is used, the slow addition of the stoichiometric amount of alkoxide or alkoxide-generating base to the medium containing the compound of Formula XIV.
When alkoxide is used, both Reaction Steps (10b) and (10c) are preferably run at temperatures within the range of about -10.degree. to 80.degree. C., the range of about 0.degree. to 25.degree. C. being more preferred. Reaction Steps (10b) and (10c) are more sluggish when alkanol is used instead of alkoxide, and more drastic conditions are required for the reaction to go to completion. Thus, higher temperatures, up to and including the boiling point of the alkanol itself, are required.
Reaction Step (10d)
Reaction Step (10d) involves the displacement of the halogen atom in a compound of Formula XIVa by dimethylamino or methylthio nucleophiles. The starting material, a compound of Formula XIVa, is prepared according to Reaction Step (10a), and Y.sub.4 is limited to C.sub.1 -C.sub.2 alkyl and CF.sub.3.
For this reaction, the compound of Formula XIVa is suspended or dissolved in an inert solvent, such as acetonitrile or THF. At least one equivalent of the nucleophilic species and at least two equivalents of a base are then contacted with the starting material. The first equivalent of base is believed to neutralize the sulfonamido proton. The second equivalent of base generates mercaptide or --N(CH.sub.3).sub.2 from the mercaptan or the dialkylamine. Suitable bases include sodium hydride, sodium methoxide and sodium hydroxide.
Suitable reaction temperatures are within the range of about -10.degree. to 80.degree. C., with a range of about 0.degree. to 25.degree. C. being preferred. The product may be isolated by dilution of the reaction mixture with water, mild acidification and filtration.
Compounds of Formula IX, which are intermediates in the preparation of the compounds of Formula II--as described in Equation 8, can also be prepared by the procedures shown in Equations 11 and 12. ##STR47## wherein A, R.sub.1 and R.sub.1.sup.' are as described in Equation 1.
The o-nitroanilines of Formula XVII are well known in the art. The method of converting compounds XVII to compounds VIII is analogous to that described in Equation (8c). The procedures for converting compounds VIII to compounds IX are described in Equation (8a). ##STR48## wherein A, R.sub.1, and R.sub.1.sup.' are as described in Equation 1;
B is Cl or Br; and
M is Na or K.
In Step (12a), the compounds of Formula XVIII, which are well known in the art, are reacted with benzyl mercaptan in the presence of an equivalent amount of a base such as sodium or potassium hydroxide. The preferred solvent for this reaction is an alcohol such as methyl, ethyl or isopropyl alcohol. The reaction can be carried out at temperatures between 25.degree. and 80.degree. but temperatures of 50.degree.-80.degree. C. are preferred. The products of Formula XIX are isolated by cooling the reaction mixture to 0.degree.-20.degree., filtering off the precipitated product, and washing this solid with water to remove the by-product alkali halide.
In Step (12b), the compound of Formula XIX is suspended in a mixture of 85-95% acetic acid and 5-15% water. This suspension is treated with at least three molar equivalents of chlorine at 0.degree.-20.degree.. When a clear solution is obtained, the reaction solution is quenched in an excess of ice water and extracted with a solvent such as methylene chloride, chloroform or 1-chlorobutane. The products of Formula VIII are isolated by concentrating this solvent extract in vacuo to remove the solvent and the by-product benzyl chloride. The products are oils or low melting solids and may be used directly in the next step or recrystallized first from such solvents as cyclohexane or 1-chlorobutane.
Compounds of Formula IX, in which A includes certain fluoroalkylamine moieties can also be prepared by the procedure shown in Equation 12a. ##STR49## wherein R.sub.1 and R.sub.1.sup.' are as previously described; R.sub.3 is C.sub.1 -C.sub.4 alkyl, and G is F, Cl, Br or CF.sub.3.
The reaction described in Equation 12a is accomplished by heating a mixture of the sulfonamide IX, one or two equivalents of the fluoroolefin and a catalytic amount of base in dimethylformamide solution in a pressure vesel at a temperature of between 60.degree. and 130.degree. until a pressure drop is no longer observed. Appropriate bases for this reaction include potassium hydroxide, sodium hydroxide, sodium hydride and sodium metal. The products of the reaction are isolated by quenching the reaction mixture in a large excess of water and extraction with n-butyl chloride or diethylether. Evaporation of the solvent yields the desired sulfonamides IXa as viscous oils.
Compounds of Formula IX in which A includes a benzyloxyamine group may also be prepared by the procedure described in Equation 12b. ##STR50## wherein R.sub.1, R.sub.1.sup.', R.sub.3, R.sub.7 and R.sub.9 are as previously described.
In the first step of Equation 12b, a sulfonyl chloride of Formula XIII is reacted with an appropriate benzyloxyamine, taken in excess to act as an acid acceptor, in diethyl ether or tetrahydrofuran solution at 0.degree.-10.degree.. The reaction is completed by stirring at ambient temperature for 4-24 hours. The solvent is evaporated and the product sulfonamide IXc purified by washing the residue with water to remove the byproduct amine hydrochloride.
In the second step of Equation 12b, the sulfonamide of Formula IXc is stirred at ambient temperature for 18-24 hours with an excess of both an alkyl iodide and anhydrous potassium carbonate or sodium carbonate in acetone or 2-butanone solution. The solvent is evaporated and the residue partitioned between methylene chloride and water. Concentration of the methylene chloride solution affords the compounds of Formula IXd as pale yellow oils.
The compounds of Formula IXd may be converted to compounds of Formula Xd by the procedure described in Equation 12c. ##STR51## wherein R.sub.1, R.sub.1.sup.', R.sub.3, R.sub.7 and R.sub.9 are as previously described.
The conversion in Equation 12c is accomplished in the following manner: A solution of the nitro compound IXd in 90% aqueous acetic acid is treated with an excess of iron powder (5 g--atom/mole of IXd) at 80.degree.-90.degree. in several portions. After heating an additional 20 minutes, charcoal is added and the solution filtered through Celite.RTM. and concentrated in-vacuo. The residue is made strongly alkaline with 20% sodium hydroxide then extracted with methylene chloride. Concentration of the organic solution yields the anilines of Formula Xd as viscous oils.
The compounds of Formula Xd may be converted to the compounds of Formula I by the procedures described in Equations 1-8.
Compounds of Formula I in which R.sub.2 is hydrogen may be prepared by the procedure described in Equation 12d. ##STR52## wherein R.sub.1, R.sub.1.sup.', R.sub.5 -R.sub.9 and W are as described previously.
In the reaction of Equation 12d, an excess of boron tribromide is added to a suspension of the compound of Formula Ih in a solvent such as benzene, toluene or xylene at ambient temperature. The reaction may be completed by stirring at room temperature or it may be necessary to heat the reaction mixture up to 138.degree. for up to 24 hours. After completion, the reaction is quenched by the addition of water and the product triturated with hexane. The products of Formula 12i are solids and are isolated by filtration.
The conversion of compounds VIII to compounds IX is described in Equation (8a).

A, R.sub.1.sup.', R.sub.5 and R.sub.6 are as previously described;
R.sub.d is C.sub.1 -C.sub.3 alkyl; and T is O or NH.
In Step (13a), the compounds of Formula IIIa, which are well known in the art, are added to at least two equivalents of phosgene in an inert solvent such as xylene or chlorobenzene at 0.degree.-5.degree.. A slow stream of phosgene is then introduced and the reaction temperature raised to 130.degree. (reflux). Refluxing the reaction mixture for 1-2 hours, followed by purgation with nitrogen, filtration, and concentration yields the products of Formula IIb, as viscous oils. These compounds may be further purified by vacuum distillation.
In Step (13b), the compounds of Formula IIb are reacted with the aminoheterocycles of Formula V in an inert solvent such as methylene chloride, acetonitrile, or tetrahydrofuran at 20.degree.-50.degree. over a period of two to twenty-four hours. A catalyst, such as DABCO, may be used to accelerate the reaction. The products are isolated by removing the solvent via concentration in vacuo.
In Step (13c) the compounds of Formula Id are reacted with amines or alcohols of Formula XXI in an inert solvent such as methylene chloride, chloroform, acetonitrile or tetrahydrofuran at 20.degree.-80.degree. over a period of two to twenty-four hours.

In the procedure described in Equation 14, the compounds of Formula If are reacted with an acid chloride of Formula XXII in an inert solvent such as chloroform, methylene chloride or tetrahydrofuran at ambient temperature in the presence of an acid acceptor such as pyridine or triethylamine. The reaction takes four to twenty-four hours for completion. Both the acid chloride, XXII, and the acid acceptor may be taken in excess to hasten the completion of the reaction. The products, Ig, are isolated by filtering-off the by-product amine hydrochloride and concentrating the filtrate in vacuo. The crude products thus obtained may be purified by recrystallization or by column chromatography.
The cmpounds of Formula IA can be prepared from the compounds of Formula I in which W is sulfur by the process described in Equation 15. ##STR56## wherein

In step (15a) the thiourea of Formula Ij is treated with an alkali or alkaline earth alkoxide, hydride, hydroxide or carbonate in tetrahydrofuran or diethyl ether suspension to obtain the salt Ik at ambient temperature up to 62.degree.. In step (15b) the salt suspension as solution is treated with the appropriately substituted iodide or bromide at 35.degree. to 62.degree. for 1-4 hours. The reaction mixture is then cooled to ambient temperature. If the product is insoluble, it may be isolated by filtration from the reaction mixture. If the product is soluble in the reaction solvent, it may be isolated by the reaction solvent, it may be isolated by evaporating the solvent and triturating the residue with a solvent such as cyclohexane or 1-chlorobutane. The product Ia may be purified by recrystallization from a suitable solvent such as acetonitrile.
Agriculturally suitable salts of compounds of Formula I and Formula IA are also useful herbicides and can be prepared in a number of ways known to the art. For example, metal salts can be made by treating compounds of Formula 1 with a solution of an alkali or alkaline earth metal salt having a sufficiently basic anion (e.g. hydroxide alkoxide, carbonate or hydride) quaternary amine salts can be made by similar techniques.

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. High strength compositions are used primarily as concentrates which are to be diluted prior to ultimate use. 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 VI.

Lower or higher levels of active ingredient can be 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, "Encyclopedia 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 can 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", 5th Ed., McGraw-Hill, New York, 1973, pp. 8-57ff.

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 theaters, around billboards, highway and railroad structures. Alternatively, some of the subject compounds are useful for the selective pre- or post-emergence weed control in crops, such as corn, wheat and rice. By properly selecting rate and time of application, compounds of this invention may be used also to modify plant growth beneficially.
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, including their use as selective or general herbicides, the crop species involved, the amount of foliage present, the species of weeds to be controlled, 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 0.001 to 10 kg/ha with a preferred range of 0.03 to 5 kg/ha. In general, the higher rates of application from within this range will be selected for adverse conditions, where extended persistence in soil is desired, or for nonselective weed control purposes.
The compounds of Formula I may be combined with other herbicides and are particularly useful in combination with substituted urea herbicides such as 3-(3,4-dichlorophenyl)-1,1-dimethyl urea; the triazines such as 2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine: the uracils such as 5-bromo-3-sec-butyl-6-methyluracil; N-(phosponomethyl)glycine; 3-cyclohexyl-1-methyl-6-dimethylamino-s-triazine-2,4(1H,3H)-dione; N,N-dimethyl-2,2-diphenylacetamide; 2,4-dichlorophenoxyacetic acid (and closely related compounds; 4-chloro-2-butynyl-3-chlorophenylcarbamate; diisopropylthiolcarbamic acid; ester with 2,3-dichloroallyl alcohol; diisopropylthiolcarbamic acid, S-(2,3,3-trichloroallyl)ester; ethyl-N-benzoyl-N-(3,4-dichlorophenyl)-2-aminopropionate; 1,2-dimethyl-3,5-diphenylpyrazolium methylsulfate; methyl 2-[4-(2,4-dichlorophenoxy)-phenoxy]propanoate; 4-amino-6-tert-butyl-3-(methylthio)-1,2,4-triazin-5(4H)-one; 3-(3,4-dichlorophenyl)-1-methoxy-1-methylurea; 3-isopropyl-1H-2,1,3-benzothiodiazin-(4)-3H-one-2,2-dioxide; .alpha.,.alpha.,.alpha.-trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine; 1,1'-dimethyl-4,4'-bipyridinium ion; monosodium methanearsonate; 2-chloro-2',6'-diethyl(methoxymethyl)acetanilide; and 1,1-dimethyl-3(.alpha.,.alpha.,.alpha.-trifluoro-m-tolyl)-urea.
The activity of these compounds was discovered in greenhouse tests. The tests are described and the data resulting from them are shown below.
Test Procedure 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 pre-emergence with a nonphytotoxic solvent solution of the compounds. 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 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. Other containers of the above mentioned weeds and crops were treated pre- or post-emergence with the same nonphytotoxic solvent so as to provide a solvent control. A set of untreated control plants was also included for comparison. Pre-emergence and post-emergence 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 using the following rating system and symbols:

Test Procedure B
Two plastic bulb pans were filled with fertilized and limed Fallsington silt loam soil. One pan was planted with corn, sorghum, Kentucky bluegrass and several grassy weeds. The other pan was planted with cotton, soybeans, purple nutsedge (Cyperus rotundus), and several broadleaf weeds. The following grassy and broadleaf weeds were planted: crabgrass (Digitaria sanguinalis), barnyardgrass (Echinochloa crusgalli), wild oats (Avena fatua), johnsongrass (Sorghum halepense), dallisgrass (Paspalum dilatatum), giant foxtail (Setaria faberii), 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 12.5 cm diameter plastic pot was also filled with prepared soil and planted with rice and wheat. Another 12.5 cm pot was planted with sugarbeets. The above four containers were treated pre-emergence with several test compounds within the scope of the invention.
Twenty-eight days after treatment, the plants were evaluated and visually rated for response to the chemical treatments utilizing the rating system described previously for Test A. The data are summarized in Test B.

Test Procedure C
Twenty-five cm diameter plastic pots filled with Fallsington silt loam were planted to soybeans, cotton, alfalfa, corn, rice, wheat, sorghum, velvetleaf (Abutilon theophrasti), sesbania (Sesbania exaltata), Cassia (Cassia tora), morningglory (Ipomoea hederacea), jimsonweed (Datura stramonium), cocklebur (Xanthium pennsylvanicum), crabgrass (Digitaria spp.), nutsedge (Cyperus rotundus), 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 test chemicals dissolved in a nonphytotoxic solvent. Fourteen days after treatment, all species were compared to untreated controls and visually rated for response to treatment. The rating system was as described previously for test A. The data are presented in Test C. It is obvious that some of the compounds have utility for selective weed control in crops such as wheat and rice.

Test Procedure D
Purple nutsedge (Cyperus rotundus) tubers were planted about 2 cm deep in Fallsington silt loam soil contained in 10 cm diameter plastic pots. Five tubers were planted in each pot. Compounds of this invention were dissolved in an non-phytotoxic diluent and sprayed at 560 l/ha in four methods of application: soil surface, tuber/soil, soil incorporated, and post-emergence. The soil surface spray consisted of spraying the compound on the surface of the firmed covering soil. The tuber/soil spray consisted of spraying the compound on exposed tubers and subtending soil before adding the untreated covering soil. Soil incorporated treatment consisted in mixing the compound with the covering soil before using it to cover the tubers. The post-emergence treatment was sprayed on nutsedge foliage and the surrounding soil surface when nutsedge had emerged and grown to a height of about 12 cm. Pots receiving the post-emergence treatments were placed directly in the greenhouse. Pots receiving the other treatments were misted with about 0.3 cm water before being transferred to the greenhouse. Response ratings assessed after four weeks are recorded in Test D, based on the same rating system as described in procedure A.

Test Procedure E
Twenty-five cm diameter plastic pots filled with Fallsington silt loam were planted with corn (Zea mays), nutsedge (Cyperus rotundus), barnyardgrass (Echinochloa crusgalli), johnsongrass (Sorghum halepense), sorghum (Sorghum vulgare), crabgrass (Digitaria sanguinalis), cassia (Cassia tora), cocklebur (Xanthium pennsylvanicum), morningglory (Ipomoea hederacea), field bindweed (Convolvulus arvensis), jimsonweed (Datura stramonium) and velvetleaf (Abutilon theophrasti). Approximately 21/2 weeks after planting, the young plants and the soil around them were sprayed overall with the test chemicals dissolved in a non-phytotoxic solvent. Fourteen days after treatment, all species were compared to untreated controls and visually rated for response to treatment. The rating system was as described previously for Test A. The data are presented in Test E. It is obvious that these compounds have utility for selective weed control in corn.
