(a) when R.sub.5 is other than hydrogen, at least one of R.sub.3, R.sub.4, R.sub.6 and R.sub.7 is other than hydrogen and at least two of R.sub.3, R.sub.4, R.sub.6 and R.sub.7 must be hydrogen; (b) when R.sub.5 is hydrogen and all of R.sub.3, R.sub.4, R.sub.6 and R.sub.7 are other than hydrogen, then all of R.sub.3, R.sub.4, R.sub.6 and R.sub.7 must be either chlorine or methyl; and (c) when R.sub.3 and R.sub.7 are both hydrogen, at least one of R.sub.4, R.sub.5 or R.sub.6 must be hydrogen.

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

The compounds of Formula I, where W=O, may be prepared as shown below in Equation 1 by the reaction of an appropriate benzenemethanesulfonyl isocyanate, II with an appropriate aminoheterocycle, III. ##STR15## wherein

R.sub.1, R.sub.2, R.sub.3, R.sub.8 and R.sub.9 are as previously defined.

The reaction of Equation 1 is best carried out in an inert aprotic solvent such as methylene chloride, tetrahydrofuran or acetonitrile at a temperature between 20.degree. and 80.degree.. A catalytic amount of 1,4-diazabicyclo[2,2,2]octane (DABCO) may be used to accelerate the reaction. In cases in which the products are insoluble in the reaction solvent, they may be isolated by simple filtration. When the products are soluble, they may be isolated by evaporation of the solvent and trituration of the residue with solvents such as 1-chlorobutane, diethyl ether or methanol and filtration.

Compounds of Formula I in which W=S and R.sub.8 =H may be prepared by the reaction shown in Equation 2. ##STR16## wherein

R.sub.1, R.sub.2, R.sub.3, and R.sub.9 are as previously defined.

The reaction of Equation 2 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 filtration of the insoluble product.

The heterocyclic isothiocyanates, V, which are used in the procedure of Equation 2 are prepared 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, G91-7 (1973) both of which are herein incorporated by reference.

The benzenemethanesulfonyl isocyanates of Formula II may be prepared as shown in Equation 3, by phosgenation of the sulfonamides of Formula IV in the presence of butyl isocyanate. The sulfonyl isocyanates of Formula II may also be prepared, as shown in Equation 4, by phosgenation of the butyl ureas of Formula VI. ##STR17## wherein

R.sub.1, R.sub.2 and R.sub.9 are as previously defined.

The above reaction is carried out by heating a mixture of the appropriate sulfonamide (IV), an alkyl isocyanate such as butyl isocyanate and a catalytic amount of a tertiary amine such as 1,4-diazabicyclo[2,2,2]octane (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 at 125.degree.-135.degree. until an excess of phosgene is present as indicated by a permanent 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, II, which can be used without further purification. ##STR18## wherein

R.sub.1, R.sub.2 and R.sub.9 are as previously defined.

The compounds of Formula VI are conveniently prepared by stirring a mixture of the sulfonamides, IV, 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 and recrystallizing the solid product. The compounds VI are treated with phosgene and a catalytic amount of DABCO in refluxing xylene or chlorobenzene in a manner analogous to that described in Equation 3. Ihe sulfonamides of Formula IV can be prepared from the appropriately substituted benzyl chlorides or benzyl bromides VII by the sequence of reactions described in Equation 5 below. ##STR19## wherein

A is chlorine or bromine; and R.sub.1, R.sub.2 and R.sub.9 are as previously defined.

Equation (5a)

In Equation (5a) a benzyl halide of Formula VII is reacted with thiourea in protic solvents such as methanol or ethanol, or aprotic solvents such as methylene chloride or benzene. Temperatures of 40.degree.-80.degree. over one-half to 4 hours are typically required to complete the reaction. The product salts, VIII, are isolated by cooling and filtration or by concentration to remove the solvent. The salts, VIII, are generally sufficiently pure to be carried on directly to step (5b) without further purification.

Equation (5b)

In Equation (5b), the hydrochloride salts VIII (A=chlorine) are suspended in water and contacted with at least three equivalents of chlorine at between 5.degree. and 20.degree.. When the corresponding hydrobromide salts VIII (A=bromine) are used, it is generally advantageous to exchange the bromide ion for the nitrate ion before chlorination by treatment with an aqueous solution of one equivalent of silver nitrate; the precipitated silver bromide is removed by filtration and the filtrate treated as described above. The product sulfonyl chlorides of Formula IX are isolated by filtration and washing with water. No further purification of the sulfonyl chlorides IX is necessary.

Equation (5c)

In Equation (5c), the sulfonyl chlorides of Formula IX are suspended in an aprotic solvent such as diethyl ether, 1-chlorobutane, methylene chloride, or tetrahydrofuran and contacted with an excess of anhydrous ammonia at a temperature of 0.degree. to 25.degree.. The product sulfonamides of Formula IV are isolated by filtration and washing with water to remove the by-product ammonium chloride and concentrating the organic solution. Frequently, the crude sulfonamides may be used directly to prepare the sulfonyl isocyanates of Formula II. However, they may also be purified first by recrystallization from a suitable organic solvent such as ethanol, acetonitrile or chloroform.

The synthesis of heterocyclic amine derivatives such as those depicted by Formula III has been reviewed in "The Chemistry of Heterocyclic Compounds", a series published by Interscience Publ., New York and London. Aminopyrimidines are described by D. J. Brown in "The Pyrimidines", Vol. XVI of the above series.

The synthesis of the bicyclic pyrimidines of Formula III is described in the following references:

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 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. Detailed examples of such techniques are given in U.S. Pat. No. 4,127,405, the disclosure of which is herein incorporated by reference.

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 diluent(s). More specifically, they will contain these ingredients in the following approximate proportions:

TABLE 10______________________________________ Weight Percent* Active 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, New Jersey, 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, New Jersey, 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, 1973, pp. 8-57ff.

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

EXAMPLE 19

______________________________________Granule______________________________________Wettable Powder of Example 18 5%attapulgite granules 95%(U.S.S. 20-40 mesh; 0.84-0.42 mm)______________________________________

A slurry of wettable powder containing .apprxeq.25% solids is sprayed on the surface of attapulgite granules in a double-cone blender. The granules are dried and packaged.

EXAMPLE 20

______________________________________Extruded Pellet______________________________________N--[(4-methoxy-6-methylpyrimidin-2-yl)aminocarbonyl]-1- 25%(2-nitrophenyl)methanesulfonamideanhydrous sodium sulfate 10%crude calcium ligninsulfonate 5%sodium alkylnaphthalenesulfonate 1%calcium/magnesium bentonite 59%______________________________________

The ingredients are blended, hammer-milled and then moistened with about 12% water. The mixture is extruded as cylinders about 3 mm diameter which are cut to produce pellets about 3 mm long. These may be used directly after drying, or the dried pellets may be crushed to pass a U.S.S. No. 20 sieve (0.84 mm openings). The granules held on a U.S.S. No. 40 sieve (0.42 mm openings) may be packaged for use and the fines recycled.

The active ingredient is dissolved in a solvent and the solution is sprayed upon dedusted granules in a double-cone blender. After spraying of the solution has been completed, the material is warmed to evaporate the solvent. The material is allowed to cool and then packaged.

EXAMPLE 27

______________________________________Granule______________________________________N--[(4,6-dimethylpyrimidin-2-yl)aminocarbonyl] -1- 80%(2-nitrophenyl)methanesulfonamidewetting agent 1%crude ligninsulfonate salt (containing 10%5-20% of the natural sugars)attapulgite clay 9%______________________________________

The ingredients are blended and milled to pass through a 100 mesh screen. This material is then added to a fluid bed granulator, the air flow is adjusted to gently fluidize the material, and a fine spray of water is sprayed onto the fluidized material. The fluidization and spraying are continued until granules of the desired size range are made. The spraying is stopped, but fluidization is continued, optionally with heat, until the water content is reduced to the desired level, generally less than 1%. The material is then discharged, screened to the desired size range, generally 14-100 mesh (1410-149 microns), and packaged for use.

Utility

The compounds of the present invention are 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, parking lots, drive-in theaters, around billboards, highway and railroad structures or under perimeter fences. Alternatively, the subject compounds are useful for the selective pre- or postemergence weed control in crops, such as wheat, barley, corn, rice and soybeans.

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 0.01 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 herbicides, examples of which are those of the triazine, triazole, uracil, urea, amide, diphenylether, carbamate and bipyridylium types. Especially useful are combinations of the compounds of this invention with S-(4-chlorobenzyl)-N,N-diethylthiolcarbamate; 2-chloro-2',6'-diethyl-N-(butoxymethyl)acetanilide; S-ethyl-N,N-hexamethylenethiolcarbamate; 1-.alpha.,.alpha.-dimethylbenzyl-3-p-tolylurea; 1-(.alpha.,.alpha.-dimethylbenzyl)-3-methyl-3-phenylurea; 2,4-dichlorophenyl-3-methoxy-4-nitrophenyl ether; 2,4,6-trichlorophenyl-4'-nitrophenyl ether; 4-(2,4-dichlorobenzoyl)-1,3-dimethyl-5-pyrazolyl-p-toluenesulfonate; O-ethyl-O-(3-methyl-6-nitrophenol)-N-sec-butyl phosphoramid-thioate; S-(1-methyl-1-phenethyl)piperidine-1-carbathioate; 2-chloro-2',6'-diethyl-N-(N-propoxyethyl)acetanilide; 4-ethoxymethoxybenz-2',3'-dichloranilide; 2-benzthiazol-2-iloxy-N-methylacetoanilide; 5-t-butyl-3-(2,4-dichloro-5-isopropoxyphenyl)-1,3,4-oxadiazol-2-one; 3',4'-dichloropropionanilide; and N-(1-ethylpropyl)-2,6-dinitro-3,4-xylidine.

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.), barnyardgrass (Echinochloa crusgalli), wild oats (Avena fatua), cassia (Cassia tora), morningglory (Ipomoea sp.), cocklebur (Xanthium sp.), sorghum, corn, soybean, rice, wheat and nutsedge tubers (Cyperus rotundus) were planted in a growth medium and treated preemergence with the chemicals dissolved in a non-phytotoxic solvent. At the same time, cotton having five leaves (including cotyledonary ones), bush beans with the third trifoliate leaf expanding, crabgrass, barnyardgrass and wild oats with two leaves, cassia with three leaves (including cotyledonary ones), morningglory and cocklebur with four leaves (including the cotyledonary ones), sorghum and corn with four leaves, soybean with two cotyledonary leaves, rice with three leaves, wheat with one leaf, and nutsedge with three to five leaves were sprayed. Treated plants and controls were maintained in a greenhouse for sixteen days, whereupon all species were compared to controls and visually rated for response to treatment. The ratings 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 effects;

S=albinism;

U=unusual pigmentation; and

6Y=abscised buds or flowers.

The ratings for the compounds tested by this procedure are presented in Table A. It will be seen that certain of the compounds tested have utility for selective weed control in corn, rice and wheat.

Test 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 pensylvanicum), 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 Table B.

It should be noted that some of the compounds tested are useful as pre- or post-emergence treatment for weed control in crops such as wheat.

Test C

Twenty-five cm diameter plastic pots filled with Fallsington silt loam were planted with soybeans, cotton, alfalfa, corn, rice, wheat, sorghum, velvetleaf (Abutilon theophrasti), sesbania (Sesbania exaltata), Cassia (Cassia tora), 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). 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. Two weeks 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 Table C. Selected compounds tested by this procedure are useful for the post-emergence control of weeds in wheat, corn, rice and soybeans.

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), shepherd's purse (Capsella bursa-pastoris), Matricaria inodora, black nightshade (Solanum nigrum), yellow rocket (Barbarea vulgaris), wild mustard (Brassica kaber), and wild buskwheat (Polygonum convolvulus). The above two pans were heated 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 nonphytotoxic solvent and sprayed over-the-top of the pans. An 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 D. One of the compounds has utility for pre- and or post-emergence weed control in wheat and barley.

A series of simulated rice paddy tests were conducted in a greenhouse. Compounds selected from within the scope of the present invention were formulated and applied directly to the paddy water three days after transplanting of rice. "Early" plant response ratings (less than one week after application) were taken in some of the tests; "late" plant response ratings (5 to 6 weeks after application) were taken in all tests.
