The compounds of this invention of Formula I, above, there Q is O, S or SO.sub.2, can be prepared, as shown in Equation 1, by reaction of the appropriate sulfonyl isocyanate of Formula II, where Q is O, S or SO.sub.2, with the appropriate amine of Formula III, where R and A are as previously defined in the Summary of the Invention above. ##STR4##

The reaction of Equation 1 is most conveniently carried out by addition of a solution of the sulfonyl isocyanate II in an inert organic solvent such as methylene chloride, acetonitrile, xylene or similar solvents to a solution or suspension of the amine III in the same solvent. Many compounds of Formula I are insoluble in the reaction solvent, and precipitate from it. They can be collected and purified by trituration with, or crystallization from, an appropriate solvent.

Those compounds of Formula I which are soluble in the reaction solvent can be isolated by evaporation of the reaction solvent followed by trituration with, or recrystallization from, an appropriate solvent.

The sulfonyl isocyanates of Formula II, where Q is O, S or SO.sub.2, can be prepared from sulfonamides of Formula IV by the methods described in U.S. Pat. No. 4,379,769, issued Apr. 12, 1983 to Levitt (Equation 2). ##STR5##

Compounds of Formula Ia, where Q is other than S(O), also can be prepared by reaction of a sulfonamide of Formula IV, where Q is other than S(O) with a carbamate of Formula V in the presence of at least one molar equivalent of trimethylaluminum. ##STR6##

The reaction of Equation 3 is carried out by addition of trimethylaluminum to a solution or suspension of the sulfonamide of Formula IV in an inert solvent such as methylene chloride, 1,2-dichloroethane or toluene, followed by addition of the carbamate of Formula V and heating of the reaction mixture at the boiling point of the solvent for periods of about 4 to 48 hours. The compounds of Formula Ia can be isolated by the addition of dilute acid, and, if insoluble in the reaction solvent, the reaction products can be collected by filtration. If the reaction products are soluble in the reaction solvent, they can be isolated by evaporation of the solvent. Purification can be achieved by the methods described for Equation 1.

The compounds of Formula Ia where L and A are as previously defined, can also be prepared, as shown in Equation 4, by the reaction of a sulfonamide with a phenyl carbamate of Formula VI, by methods similar to those described in South African Patent Application No. 825,671. ##STR7##

The reactants are heated together, in the presence of an inorganic or organic base, in an inert organic solvent, such as dioxane, toluene or similar solvents, for several hours. The compounds of Formula Ia can be isolated by concentration and/or evaporation of the solvent and purification of the reaction product by methods previously described.

The compounds of Formula I, where L, R and A are as previously defined, can be prepared, as shown in Equation 5, by reaction of a sulfonyl carbamate of Formula VII and an amine of Formula III, by the methods described in South African Patent Application No. 825,042. ##STR8##

The compounds of Formula I where Q is S(O) and R and A are as previously defined can also be prepared by oxidation, by methods well known to those skilled in the art, of the compounds of Formula I where Q is S.

The sulfonamides of Formula IV can be prepared from the corresponding sulfonyl chlorides by methods well known in the art. When additional chemical reactions are required in the synthesis of sulfonamides of Formula IV, it is occasionally advantageous to convert the sulfonyl chlorides of Formula VII to a N-tert-butyl sulfonamide of Formula IX, followed by removal of the tert-butyl group; when all chemical modifications are complete, as shown in Equation 6. ##STR9##

The preparation of sulfonamides of Formula IX are well known to those skilled in the art. The removal of the tert-butyl group can be carried out by (a) stirring a solution of the sulfonamide of Formula IX in trifluoroacetic acid for several hours, or (b) heating a solution of sulfonamides IX in methanol which contains hydrogen chloride or concentrated hydrochloric acid.

The sulfonyl chlorides of Formula VIII can be prepared by the methods shown in Equations 7A and 7B, both of which are well known in the art. ##STR10##

The amines of Formula III can be prepared by the methods described in (a) U.S. Pat. No. 4,339,267, (b) European Patent Application No. 46,677, (c) European Patent Application No. 73,562, (d) South African Patent Application No. 825,405 and (e) Vol. XIII and Vol. XVI of "The Chemistry of Heterocyclic Compounds," a series published by Interscience Publishers.

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 treating compounds of Formula I with a solution of 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 contact 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 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.

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 diluent(s). More specifically, they will contain these ingredients in the following approximate proportions: ______________________________________ Weight Active  Percent* Ingredient Diluent(s) Surfactant(s) ______________________________________ Wettable Powders 20-90      0-74      1-10 Oil Suspensions, 3-50     40-95      0-15 Emulsions, Solutions, (including Emulsifiable Concentrates) Aqueous Suspension 10-50     40-84      1-20 Dusts          1-25     70-99     0-5 Granules and Pellets 0.1-95      5-99.9   0-15 High Strength 90-99      0-10     0-2 Compositions ______________________________________ *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 will. 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.

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, many of the subject compounds should be useful for the selective post-emergence weed control in crops, especially wheat.

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 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 0.005 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 persistence 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 greenhouse test. The test procedure and results follow.

Seeds of crabgrass (Digitaria sp.), barnyardgrass (Echinochloa crusgalli), wild oats (Avena fatua), sicklepod (Cassia obtusifolia), morningglory (Ipomoea sp.), cocklebur (Xanthium sp.), sorghum, corn, soybean, sugar beet, cotton, rice, wheat and purple nutsedge (Cyperus rotundus) tubers were planted and treated pre-emergence with the test chemicals dissolved in a non-phytotoxic 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:

It will be seen from the data for some of the compounds tested that wheat is tolerant of rates of application which provide excellent control of several problem weed species. Therefore, compounds from within the scope of the invention should be useful for selective post-emergence weed control in cereal crops, such as wheat. ##STR36## __________________________________________________________________________ Cmpd.
