DETAILED DESCRIPTION OF THE INVENTION

Synthesis

The compounds of Formula I can be prepared by contacting an appropriate sulfonyl isocyanate III with and S,S-dialkyl-N-(heterocyclic)sulfilimine II as illustrated in Equation 1. (L, R.sub.a, R.sub.b, and A are as previously defined.) ##STR8##

The reaction of Equation 1 is best carried out in an inert aprotic solvent, such as methylene chloride, tetrahydrofuran, acetonitrile, ether or chloroform, at temperatures ranging from about -20.degree. to 50.degree. C. In some cases, the desired product may crystallize from the reaction medium and may be filtered. Reaction products which are soluble in the reaction medium may be isolated by evaporation of the solvent, trituration of the residue with solvents such as diethyl ether, ethyl acetate, 1-chlorobutane or hexane. Chromatography (e.g., silica gel) may also be necessary for purification.

The sulfonyl isocyanates III used as starting materials are generally known in the art and can be prepared by known methods. One method involves reacting an appropriate benzene or heterocyclic sulfonamide with phosgene in the presence of an alkyl isocyanate, such as n-butyl isocyanate, and a tertiary amine catalyst, such as 1,4-diazabicyclo [2.2.2]octane, at reflux in a solvent such as xylene or chlorobenzene. See H. Ulrich and A. A. Y. Sayigh, Newer Methods of Preparative Organic Chemistry, Vol. VI, p. 223-241, Academic Press, New York and London, W. Foerst Ed.

The sulfonyl isocyanates III can also be prepared from sulfonamides by a two step procedure involving (a) reacting the sulfonamides with an alkyl isocyanate in the presence of a base such as K.sub.2 CO.sub.3 at reflux in an inert solvent such as 2-butanone, forming an alkylsulfonylurea, and (b) reacting this compound with phosgene and tertiary amine catalyst at reflux in xylene solvent.

The preparation of sulfonamides from ammonium hydroxide and sulfonyl chlorides is widely reported in the literature, e.g. Crossley et al., J. Am. Chem. Soc., 60, 2223 (1938). Certain sulfonyl chlorides are best prepared by chlorosulfonation of a substituted benzene, naphthalene, or thiophene in carbon tetrachloride according to the teaching of H. T. Clarke et al., Org. Synth. Coll., Vol. 1, 2nd Ed. 1941, p. 85. Other sulfonyl chlorides can be made by diazotization of the appropriate amine with sodium nitrite in HCl, followed by reaction of the diazonium salt with sulfur dioxide and cuprous chloride in acetic acid according to the teachings of H. L. Yale and F. Sowinski, J. Org. Chem., 25, 1824 (1960).

Reference to the following patents and patent applications, the disclosures of which are hereby incorporated by reference, is suggested for further details regarding the preparation of the sulfonyl isocyanates III: U.S. Pat. No. 4,169,719, U.S. Pat. No. 4,127,405; U.S. Pat. No. 4,383,113; U.S. Pat. No. 4,394,506; U.S. Pat. No. 4,120,691; U.S. Pat.

No. 1128042; European Patent Application No. 82301500.3, published Nov. 17, 1982; European Patent Application No. 81305160.4, published May 12, 1982; and copending U.S. patent application Ser. No. 410,993, filed Aug. 27, 1982; U.S. Ser. No. 406,191, filed Aug. 11, 1982, U.S. Ser. No. 499,443, filed May 31, ,983, and U.S. Ser. No. 436,631, filed Oct. 10, 1982.

The sulfilimine (II) starting materials may be made in a number of ways. S,S-Dimethyl-N-(4,6-di-methylpyrimidin-2-yl)sulfilimine and S,S-dimethyl-N-(4-methylpyrimidin-2-yl)sulfilimine are taught by T. L. Gilchrist, C. J. Harris and C. W. Rees in J.C.S. Chem. Comm., 486 (1974). The procedure taught in this article can be adapted to prepare other sulfilimines of Formula II as shown in Equation 2. ##STR9## A heterocyclic amine IV is contacted successively with tert-butyloxy chloride, a dialkylmercaptide and sodium methoxide.

The reaction may be best carried out in an inert aprotic solvent, such as methylene chloride, chloroform or ethyl acetate at temperatures between -60.degree. to 60.degree. C. for 1-48 hours with ambient pressure. The resulting solution may be washed with water. In some cases, the desired product may crystallize from the organic solvent and may be filtered. Reaction products which are soluble in the organic solvent may be isolated by evaporation of the solvent after the organic solution is dried over a drying agent such as sodium sulfate or magnesium sulfate and trituration of the residue with solvents such as diethyl ether, 1-chlorobutane or hexane. Chromatography (e.g., silica gel) may also be necessary for purification.

Sulfilimines of Formula II can also be prepared by the general procedure illustrated in Equation 3. ##STR10## The appropriate amine IV is contacted with the appropriate dialkylmercaptide in the presence of N-chlorosuccinimide.

The reaction is best carried out in an inert aprotic solvent, such as methylene chloride, chloroform or ethyl acetate at temperatures between -30.degree. to 60.degree. C. for 1-48 hours with ambient pressure. The resulting solution is then washed with aqueous sodium hydroxide solution and then water. The desired product can be isolated as described in the previous paragraph.

Yet another method for preparing the sulfilimines II is shown in Equation 4. ##STR11##

The reaction of Equation 4 may be best carried out in an inert aprotic solvent, such as methylene chloride or chloroform at temperatures between -70.degree. to 70.degree. C. for 1-48 hours with ambient pressure. The resulting solution may be washed with sodium hydroxide aqueous solution and then water. The desired product can be isolated as described in the previous paragraph.

Heterocyclic amines of Formula IV and methods for preparing them are known in the art. The synthesis of heterocyclic amines such as those of Formula IV has been reviewed in "The Chemistry of Heterocyclic Compounds", a series published by Interscience Publ., New York and London. 2-Aminopyrimidines are described by D. J. Brown in "The Pyrimidines", Vol. XVI of this series. 2-Amino-1,3,5-triazines can be prepared according to methods described by E. M. Smolin and L. Rapaport in "s-Triazines and Derivatives", Vol. XIII of the same series. The synthesis of triazines is also described by F. C. Schaefer, U.S. Pat. No. 3,154,547 and by K. R. Huffman and F. C. Schaefer; J. Org. Chem., 28, 1816 (1963). See also U.S. Ser. No. 434,038, filed Oct. 20, 1982, European Patent Application No. 80300505.7, published Sept. 17, 1980 (Pub. No. 15,683).

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:

TABLE XVIII______________________________________ 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., 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, 1973, pp. 8-57ff.

Utility

Test results indicate that the compounds of the present invention are active herbicides. They should 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. Alternatively, the subject compounds should be useful for the selective pre- or post-emergence weed control in crops, such as wheat and rice.

The rates of application for the compounds of the invention are determined by a number of factors, including their use as selective or general herbicides, the crop species involved, the type of weeds to be controlled, weather and climate, formulations selected, mode of application, amount of foilage present, etc. In general terms, the subject compounds should be applied at levels of around 0.05 to 10 kg/ha, the lower rates being suggested for use on lighter soils and/or those having a low organic matter content, for selective weed control or for situations where only short-term persistance is required.

The compounds of the invention may be used in combination with one another or 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 sp.), barnyard-grass (Echinochloa crusgalli), wild oats (Avena fatua), sicklepod (Cassia obtusifolia), morningglory (Ipomoea sp.), cocklebur (Xanthium sp.), sorghum corn, soybean, rice, wheat, and nutsedge (Cyperus rotundus) tubers were planted and treated pre-emergence with the test chemicals dissolved in a nonphytotoxic solvent. At the same time, these crop and weed species, along with cotton and bush bean, 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:

C=chlorosis/necrosis: D=defoliation: E=emergence inhibition: G=growth retardation: H=formative effect: U=unusual pigmentation; and 6Y=abscised buds or flowers.

The compounds tested are highly active herbicides. Several of the compounds in Table A selectively control weeds applied pre- or post-emergence to wheat. ##STR59##

Several of the compounds of this invention were further tested in a pre-emergence herbicide screen as described in Test B.

Test B

Two plastic bulb pans were filled with fertilized and limed Woodstown sandy loam. One pan was planted with corn, sorghum, Kentucky bluegrass and several grass weeds. The other pan was planted with cotton, soybeans, purple nutsedge (Cyperus rotundus), and several broadleaf weeds. The following grass 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 pensylvanicum), pigweed (Amaranthus retroflexus), morningglory (Ipomoea hederacea), sicklepod (Cassia obtusifolia), 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 sugar beets. 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 for Compound 1 are summarized in Table B. Compound 1 appeared to be one of the most active of the compounds tested in this screen; however, the results for the other compounds tested indicate that they, too, have high herbicidal activity when applied at low rates as pre-emergence treatments on soil.

A number of compounds were also treated to more accurately define their utility in post-emergence applications.

Test C

The test chemicals, dissolved in a non-phytotoxic solvent, were applied in an overall spray to the foliage and surrounding soil of selected plant species. One day after treatment, plants were observed for rapid burn injury. Approximately fourteen days after treatment, all species were visually compared to untreated controls and rated for response to treatment. The rating system was as described previously for Test A. The data are presented in Table C.

All plant species were seeded in Woodstown sandy loam soil and grown in a greenhouse. The following species were grown in soil contained in plastic pots (25 cm diameter by 13 cm deep): soybeans, cotton, alfalfa, corn, rice, wheat, sorghum, velvetleaf (Abutilon theophrasti), sesbania (Sesbania exaltata), Sicklepod (Cassia obtusifolia), morningglory (Ipomoea hederacea), jimsonweed (Datura stramonium), cocklebur (Xanthium pensylvanicum), crabgrass (Digitaria sp.), nutsedge (Cyperus rotundus), barnyardgrass (Echinochloa crusgalli), giant foxtail (Setaria faberii) and wild oats (Avena fatua). The following species were grown in soil in a paper cup (12 cm diameter by 13 cm deep): sunflower, sugar beets, and mustard. All plants were sprayed approximately 14 days after planting. Additional plant species, such as johnsongrass and field bindweed, are sometimes added to this standard test in order to evaluate unusual selectivity.

Again, Compound 1 appeared to be one of the most active compounds when applied post-emergence, and the results for this compound are presented in Table C. All of the compounds tested, however, were shown to be highly active post-emergence herbicides. Some of the compounds, for example, Compounds 3, 4, 6 and 15, show potential utility for selective post-emergence weed control in wheat.

The procedure described as Test D was performed to illustrate the potential utility of Compound 3 as a post-emergence herbicide in wheat and barley.

Test D

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 Russian thistle (Salsola kali), tansy mustard (Descuraina pinnata), smartweed (Polygonum pensylvanicum), tumble mustard (Sisymbrium altissium) kochia (Kochia scoparia), shephard's purse (Capsella bursa-pastoris), Matricaria inodora, black nightshade (Solanum nigrum), yellow rocket (Barbarea vulgaris), rapeseed (Brassica kaber) and wild buckwheat (Polygonum convolvulus). 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 test compound applied was diluted with a non-phytotoxic solvent and sprayed over-the-top of the pans. An untreated control and a solvent alone control were included for comparison. The plantings were maintained in the greenhouse for 19-21 days at which time the treatment was compared to the controls and the effects visually rated. The recorded data are presented in Table D.

A final test was designed to evaluate the potential utility of compounds from within the scope of the invention for selective weed control in rice.

Test E

The crop was transplanted into simulated paddies containing soil and propagules of barnyardgrass (Echinochloa sp.), water chestnut (Eleocharis sp.) and arrowhead (Sagittaria sp.). Three days after transplanting, the test chemicals were applied to the paddy water in a non-phytotoxic solvent at the rates shown in Table E. The paddies were maintained in a greenhouse, and plant response ratings were taken several weeks after application utilizing the rating system as described for Test A. Compounds 11 and 14 appear to have utility for weed control in transplanted rice.
