DETAILED DESCRIPTION OF THE INVENTION

Synthesis

The compounds of Formula I can be prepared from sulfonamides of Formula II and heterocyclic amines of Formula III by one or more methods described in the literature. ##STR17## Several representative routes are described below. U.S. Pat. No. 4,394,506 (issued 7/19/83) teaches the conversion of sulfonamides to sulfonyl isocyanates and sulfonyl isothiocyanates, and their subsequent coupling with heterocyclic amines of Formula III to give sulfonylureas.

U.S. Pat. No. 4,398,939 (issued 8/16/83) teaches the formation of n-butylsulfonylureas from sulfonamides followed by phosgenation to give the sulfonyl isocyanates. Alternatively, the sulfonamides can be treated with thionyl chloride followed by phosgenation to afford the sulfonyl isocyanates. Additionally, methylcarbamate derivatives of compounds of Formula III react with sulfonamides in the presence of trimethylaluminum to give sulfonylureas. U.S. Pat. No. 4,443,245 (issued 4/17/84) teaches two methods for the synthesis of sulfonylureas. Either a phenyl carbamate of a sulfonamide and a heterocyclic amine, or a sulfonamide and a phenyl carbamate of a heterocyclic amine couple to give a sulfonylurea in an inert solvent with base.

The preparation of sulfonamides from sulfonyl chlorides is widely reported in the literature; for reviews see: F. Hawking and J. S. Lawrence. "The Sulfonamides," H. K. Lewis and Co., London, 1950 and E. H. Northey, "The Sulfonamides and Allied Compounds," Reinhold Publishing Corp., New York, 1948.

Additionally, primary sulfonamides, such as those of Formula II, can be formed by removal of an N-t-butyl protecting group from the corresponding secondary sulfonamide with trifluoroacetic acid (J. D. Catt and W. L. Matier, J. Org. Chem., 39, 566 (1974)) or polyphosphoric acid (J. G. Lombardino, J. Org. Chem., 36 (1971), 1843).

The requisite sulfonyl chlorides may be synthesized by known methods or with slight modifications thereof, by one skilled in the art. Several representative teachings are listed below.

Aromatic nitro groups may be transformed into sulfonyl chlorides by reduction, diazotization and coupling with sulfur dioxide/cupric chloride as taught in U.S. Pat. No. 4,310,346 (issued 1/12/82). European Publication No. 94,821 (published 11/23/83) describes the displacement of aromatic halides with thiolate anions and subsequent oxidative chlorination to yield sulfonyl chlorides. Halogen-metal exchange of aromatic halides or proton-metal exchange of aromatics followed by quenching with sulfur dioxide gives sulfinate salts. These salts yield sulfonyl chlorides upon reaction with N-chlorosuccinimide as taught in U.S. Pat. No. 4,481,029 (issued 11/6/84). Directed proton-metal exchange of aromatic compounds has been reviewed by Gschwend and Rodriguez, Org. Reactions, 26 (1979), 1. Directed lithiation of aryl-N-t-butylsulfonamides is described by J. G. Lombardino, J. Org. Chem., 36 (1971), 1843. Also, aryllithiums may be converted directly to arylsulfonyl chlorides with sulfuryl chloride as described in S. N. Bhattacharya, et. al., J. Chem. Soc. C, (1968), 1265. Electrophilic chlorsulfonation of an aromatic ring to give a sulfonyl chloride is well known in the literature. This technique works best for alkyl aryl ethers and alkyl aromatics. Its application is described by E. H. Huntress and F. H. Carten, J. Am. Chem. Soc., 62 (1940), 511-14 and 603-4. Transformation of phenols of sulfonyl chlorides can be accomplished by the formation of a thiocarbamate, rearrangement, hydrolysis and oxidative chlorination as described by M. S. Newman and H. A. Kames, J. Org. Chem., 31 (1966), 3980.

Compounds of Formula II can be prepared by a variety of methods known in the literature. The most universal scheme, where benzyl halides of Formula IV are reacted with the appropriate reagent, is shown below. ##STR18## wherein U is SO.sub.2 NH.sub.2 or a previously described sulfonamide precursor, and X.sup.1 is Cl, Br or I and R.sub.2 is of the structure --CH(R.sub.17)--. Some specific methods are listed below.

NITRILES (R.sub.2 =CH(R.sub.17)CN) Nitriles can be prepared by nucleophilic displacement of benzyl halides, usually benzyl chlorides or bromides, with potassium or sodium cyanide. Many solvents are applicable, but frequently dimethylsulfoxide is used. Thus, a benzyl bromide of formula IV can be contacted with potassium cyanide in dimethylsulfoxide for 0.5 h to 24 h at 20.degree. to 140.degree. C. For a review of this reaction, refer to Friedrich and Wallenfels, in Rappoport. "The Chemistry of the Cyano Group", pp. 77-86, Interscience Publishers, New York, 1970. ISONITRILES (R.sub.2 =CH(R.sub.17)NC) Heavy metal cyanides and benzylhalides react to give isonitriles. The reaction is best carried out in the dark using silver cyanide and a benzyl iodide. Typical procedures are given by A. Gautier, Ann. Chem., 142 (1867), 28 and H. L. Jackson and B. C. McKusick, Org. Syn., Col. Vol. IV, 438. AZIDES (R.sub.2 =CH(R.sub.17)N.sub.3) Compounds of Formula II may be prepared by reacting an azide anion with a benzyl halide. Typically sodium azide in alcohol or wet acetone is mixed with a benzyl bromide at 20.degree.-100.degree. C. This nucleophilic displacement is reviewed in Biffin, Miller and Paul, in Patai, "The Chemistry of the Azido Group," pp. 57-119, Interscience Pub., New York, 1971. PHOSPHONATES (R.sub.2 =CH(R.sub.17)P(O)R.sub.10 R.sub.11) Alkyl phosphites are heated with benzylic halides to give phosphonates. The reaction is known as the Arbuzov reaction and it is reviewed by Arbuzov, Pure Appl. Chem., 9 (1964), 307-335. AMINES (R.sub.2 =CH(R.sub.17)NR.sub.12 R.sub.13) Tertiary amines are prepared by alkylation of a secondary amine with a benzylic halide. The reaction is well documented in the literature. Primary amines can be prepared by reduction of compounds of Formula II where R.sub.2 is azide. Generally lithium aluminum hydride or hydrogen and palladium catalyst are used. NITRO (R.sub.2 =CH(R.sub.17)NO.sub.2)

Nitrites react with benzylic halides to give benzylic nitro compounds. The reaction is usually carried out with sodium nitrite on a benzylic bromide in dimethylformamide or dimethylsulfoxide. When silver nitrite is used, diethyl ether at 0.degree.-25.degree. C. are the preferred reaction conditions. The reaction is exhaustively discussed by N. Kornblum, Org. Reactions, 12 (1962), 101.

SELLENO ETHERS (R.sub.2 =CH(R.sub.17)SeR.sub.14) Alkali alkylselenides can be prepared by in situ combination of an alkali metal t-butoxide with the selenol HSeR.sub.14 in the solvent to be used for the displacement reaction. The selenols, HSeR.sub.14, can be prepared by a variety of methods reviewed by D. L. Klayman, "Selenols and their Derivatives" in Organic Selenium Compounds: Their Chemistry and Biology, D. L. Klayman, W. H. H. Gunther ed., New York, 1973, and K. J. Irgolic and M. V. Kudchadker, "Organic Chemistry of Selenium" in Selenium, R. A. Zingaro, W. C. Copper ed., Van Nostrand Reinhold, New York, 1974.

Benzyl halides may be formed through a variety of methods described in the literature. Several are listed below.

BENZYLIC CHLORIDES (X.sup.1 =Cl) Treatment of alkyl benzene derivatives with N-chlorosuccinimide, NCS, in a suitable solvent, such as carbon tetrachloride or dichloromethane, and catalyzed by light or a free radical initiator, such as azoisobutyronitrile or benzoyl peroxide, gives the benzylic chloride. Treatment of a benzylic alcohol with thionyl chloride, either neat or in the presence of a base such as pyridine, gives the benzylic chloride. For typical examples, see H. Gilman and J. E. Kirby, J. Am. Chem. Soc., 51, 3475 (1929) and M. S. Newman, J. Am. Chem. Soc., 62, 2295 (1940). BENZYLIC BROMIDES (X.sup.1 =Br) Treatment of alkyl benzene derivatives with N-bromosuccinimide by a method analogous to the case of N-chlorosuccinimide gives the benzylic bromide. Benzylic alcohol in an inert solvent such as benzene of dichloromethane react with phosphorus tribromide to give benzylic bromides. BENZYLIC IODIDES (X.sup.1 =I) Treatment of a benzylic chloride or benzylic bromide with sodium iodide gives the benzylic iodide. The reaction, known as the Finkelstein reaction, works well in refluxing acetone. Benzylic alcohols may be treated with iodine and phosphorus (red) or phosphorus (red) and phosphorus (yellow) to give the benzylic iodide.

Compounds of Formua II, where R.sub.2 contains an oxygen functionality, such as an aldehyde or ketone, may be prepared by a variety of methods known to one skilled in the art. Two such routes are shown below. ##STR19##

Agriculturally suitable salts of compounds of Formula I 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 contacting copounds of Formula I 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.

Salts of compounds of Formula I can also be prepared by exchange of one cation for another. Cationic exchange can be effected by direct contacting of an aqueous solution of a salt of a compound of Formula I (e.g., alkali metal or quaternary amine salt) with a solution containing the cation to be exchanged. This method is most effective when the desired salt containing the exchanged cation is insoluble in water, e.g., a copper salt, and can be separated by filtration.

Exchange may also be effected by passing an aqueous solution of a salt of a compound of Formula I (e.g., an alkali metal or quaternary amine salt) through a column packed with a cation exchange resin containing the cation to be exchanged. In this method, the cation of the resin is exchanged for that of the original salt of the resin is exchanged for that of the original salt and the desired product is eluted from the column. This method is particularly useful when the desired salt is water-soluble, e.g., a potassium, sodium or calcium salt.

Acid addition salts, useful in this invention, can be obtained by reacting a compound of Formula I with a suitable acid, e.g., p-toluenesulfonic acid, trichloroacetic acid or the like.

The preparation of the compounds of this invention is further illustrated by the following examples.

FORMULATIONS

Useful formulations of the compounds of Formula I can be prepared in conventional ways. They include dusts, granules, pellets, solutions, suspensions, emulsions, wettable powders, emulsifiable concentrates and the like. Many of these may 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 primarily used as intermediates for further formulation. 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 inert diluent(s). More specifically, they will contain these ingredients in the following approximate proportions:

______________________________________ Active Weight Percent* Ingredient Diluent(s) Surfactant(s)______________________________________Wettable Powders 20-90 0-74 1-10Oil Suspensions, 3-50 40-95 0-15Emulsions, Solutions,(including EmulsifiableConcentrates)Aqueous Suspension 10-50 40-84 1-20Dusts 1-25 70-99 0-5Granules and Pellets 0.1-95 5-99.9 0-15High Strength 90-99 0-10 0-2Compositions______________________________________ *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, 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.

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 may be made by spraying the active material upon 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, 1963, pp. 8-57ff.

In the following examples, all parts are by weight unless otherwise indicated.

Example 10

______________________________________High Strength Concentrate______________________________________5-(cyanomethyl)-2-methoxy-N--[(4-methoxy- 99%6-methyl-1,3,5-triazin-2-yl)aminocarbonyl]-benzenesulfonamidetrimethylnonyl polyethylene glycol ether 1%______________________________________

The surfactant is sprayed upon the active ingredient in a blender and the mixture sifted through a U.S.S. no. 40 sieve (0.42 mm openings) prior to packaging. The concentrate may be formulated further for practical use.

EXAMPLE 11

______________________________________Wettable Powder______________________________________5-(cyanomethyl)-N--[(4,6-dimethoxypyrimidin- 65%2-yl)aminocarbonyl]-2-methoxybenzene-sulfonamidedodecylphenol polyethylene glycol ether 2%sodium ligninsulfonate 4%sodium silicoaluminate 6%montmorillonite (calcined) 23%______________________________________

The ingredients are thoroughly blended. The liquid surfactant is added by spraying upon the solid ingredients in the blender. After grinding in a hammer mill to produce particles essentially all below 100 microns, the material is reblended and sifted through a U.S.S. No. 50 sieve (0.3 mm opening) and packaged.

EXAMPLE 12

The ingredients are thoroughly blende, passed through an air mill, to produce an average particle size under 15 microns, reblended, and sifted through a U.S.S. No. 50 sieve (0.3 mm opening) before packaging.

All compounds of the invention may be formulated in the same manner.

EXAMPLE 17

______________________________________Granule______________________________________wettable powder of Example 16 15%gypsum 69%potassium sulfate 16%______________________________________

The ingredients are blended in a rotating mixer and water sprayed on to accomplish granulation. When most of the material has reached the desired range of 1.0 to 0.42 cm (U.S.S. #18 to 40 sieves), the granules are removed, dried, and screened. Oversized material is crushed to produce additional material in the desired range. These granules contain % active ingredient.

EXAMPLE 18

______________________________________Wettable Powder______________________________________5-(cyanomethyl)-N--[(4,6-dimethoxypyrimidin- 50%2-yl)-aminocarbonyl]-2-methoxybenzene-sulfonamidesodium alkylnaphthalenesulfonate 2%low viscosity methyl cellulose 2%diatomaceous earth 46%______________________________________

The ingredients are blended, coarsely hammer-milled and the air milled to produce particles of active essentially all below 10 microns in diameter. The product is reblended before packaging.

EXAMPLE 19

UTILITY

Test results indicated that the compounds of the present invention are highly active preemergent or postemergent herbicides or plant growth regulants. Many of them 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, parking lots, drive-in theaters, around billboards, highway and railroad structures. Some of the compounds have utility for selective weed control in crops such as wheat. Alternatively, the subject compounds are useful to modify plant growth.

The rates of application for the compounds of the invention are determined by a number of factors, including their use as plant growth modifiers or as herbicides, the crop species involved, the types of weeds to be controlled, weather and climate, formulations selected, mode of application, amount of foliage present, etc. In general terms, the subject compounds should be applied at levels of around 0.001 to 10 kg/ha, the lower rates being suggested for use on lighter soils and/or those having a low organic matter content, for plant growth modification or for situations where only short-term peristence is required.

The compounds of the invention may be used in combination with any other commercial herbicide; examples of which are those of the triazine, triazole, uracil, urea, amide, diphenylether, carbamate and bipyridylium types.

The herbicidal properties of the subject compounds were discovered in a number of greenhouse tests. The test procedures and results follow.

TEST A

Seeds of crabgrass (Digitaria spp.), barnyardgrass (Echinochloa crusgalli), cheatgrass (Bromus Secalinus), giant foxtail (Setaria faberii), wild oats (Avena fatua), velvetleaf (Abutilon theophrasti), morningglory (Ipomoea spp., cocklebur (Xanthium pensylvanicum), sorghum, corn, barley, soybean, sugarbeet, cotton, rice, wheat and purple nutsedge (Cyperus rotundus) tubers were planted and treated preemergence with the test chemicals dissolved in a non-phytoxic solvent. At the same time, these crop and weed species were treated with a soil/foliage application. At the time of treatment, the plants ranged in height from 2 to 18 cm. Treated plants and controls were maintained in a greenhouse for sixteen days, after which all species were compared to controls and visually rated for response to treatment. The ratings, summarized in Table A, are based on a numerical scale extending from 0=no injury, to 10=complete kill. The accompanying descriptive symbols have the following meanings:

B=burn; C=chlorosis/necrosis; D=defoliation; E=emergence inhibition; G=growth retardation; H=formative effect; U=unusual pigmentation; X=axillary stimulation; S=albinism; and 6Y=abscised buds or flowers. __________________________________________________________________________COMPOUNDS ##STR58##Compound R.sub.1 R.sub.2 X Y
