Herbicidal pyridyl sulfonamides

BACKGROUND OF THE INVENTION
This invention relates to novel N-[(pyridyl or pyrimidyl)aminocarbonyl]arylsulfonamides, to herbicidal compositions containing them and to methods of using them to control the growth of undesired vegetation.
New compounds effective for controlling the growth of undesired vegetation are in constant demand. In the most common situation, such compounds are sought to selectively control the growth of weeds in useful crops such as cotton, rice, corn, wheat and soybeans, to name a few. Unchecked weed growth in such crops can cause significant losses, reducing profit to the farmer and increasing costs to the consumer. In other situations, herbicides are desired which will control all plant growth. Examples of areas in which complete control of all vegetation is desired are areas around fuel storage tanks, ammunition depots and industrial storage areas. These are many products commercially available for these purposes, but the search continues for products which are more effective, less costly and environmentally safe.
A number of different types of N-[(heterocyclic)aminocarbonyl]arylsulfonamides are known as herbicides. Two of the first patents to issue on such compounds are U.S. Pat. Nos. 4,169,719 and 4,127,405, issued on Oct. 2, 1979 and Nov. 28, 1978, respectively. These patents disclose compounds of the general formula ##STR1## where R.sub.1 can be optionally substituted benzene, thiophene, pyrrole, furan or unsubstituted naphthalene,
and Y is N or CH.
Subsequent patents which have issued have disclosed related compounds with different N-heterocycles. For example, U.S. Pat. No. 4,293,330, issued on Oct. 6, 1981, discloses pyridyl sulfonylureas, and U.S. Pat. No. 4,221,585, issued on Sept. 9, 1980, disclose 4-pyrimidyl sulfonylureas. Nowhere in the art has there been any indication that N-(pyridyl or pyrimidyl)sulfonylurea derivatives, in which the pyridyl or pyrimidyl moiety is substituted ortho- to the sulfonylurea bridge with an electron-withdrawing group, would exhibit high herbicidal activity.
West German patent application No. 3151450A, published 7/14/83, filed by Celamerck discloses sulfamate sulfonylureas of the following general structure. ##STR2##
European Publication No. 126,711, published 11/28/84 discloses herbicidal sulfonylureas of the formula ##STR3## where, in part, X is O, S, --NR.sub.5 --, ##STR4## --CH.dbd.CH-- or an annelated phenyl ring; Q is, inter alia, halogen, C.sub.1 -C.sub.4 alkyl, nitro, C.sub.1 -C.sub.4 alkoxycarbonyl, C.sub.1 -C.sub.4 alkylsulfonyl;
R.sub.2 and R.sub.3 are independently H, halogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, etc.; or
Q and R.sub.2 together can also form a 2-4 membered carbon chain, which may still contain an oxygen or sulfur atom, or the group NR.sub.5 ;
R.sub.1 is H, halogen, nitro or a group ##STR5## R.sub.4 is H, halogen, C.sub.1 -C.sub.4 alkyl, methoxy, nitro or trifluoromethyl;
Z is O or S;
R.sub.5 is H, C.sub.1 -C.sub.4 alkyl or C.sub.3 -C.sub.4 alkenyl.

DETAILED DESCRIPTION OF THE INVENTION
Synthesis
The compounds of Formula I can be prepared by reacting an appropriate aminoheterocycle of Formula II with an appropriately substituted sulfonyl isocyanate or sulfonyl isothiocyanate of Formula III, as shown in in Equation 1.
Equation 1 ##STR10## wherein A, J, W.sub.1 and R are as previously defined.
The reaction of Equation 1 is best carried out in inert organic solvents such as methylene chloride, tetrahydrofuran, or acetonitrile, at ambient pressure and temperature. The mode of addition is not critical; however, it is often convenient to add the sulfonyl isocyanate to a stirred suspension or solution of the aminoheterocycle. Since such isocyanates usually are liquids, their additions can be easily controlled.
The reaction is generally exothermic. In some cases, the desired product is insoluble in the warm reaction medium and crystallizes from it in pure form. Products soluble in the reaction medium are isolated by evaporation of the solvent, trituration of the solid residue with solvents such as 1-chlorobutane or ethyl ether, and filtration.
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.
Sulfonyl isothiocyanates can be prepared according to the methods described by K. Hartke, Arch. Pharm., 299, 174 (1966).
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).
More specifically, the compounds of this invention may be prepared as described above by the route illustrated below. ##STR11##
Reference to the following patents 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. 4,238,621 and EP-A-107,979.
Appropriately substituted aminoheterocycles of Formula II, where R=H and A is a substituted 2-pyridyl or 4-pyrimidyl moiety are generally known in the art and are reviewed in The Chemistry of Heterocyclic Compounds, "Pyridine and its Derivatives", Vol. 14, Suppl. Parts I and III (1974), and "The Pyrimidines" (1962) and Suppl. 1 (1970), (John Wiley and Sons, Inc., New York). Commonly used starting materials for the synthesis of such substituted heterocycles are malononitrile, cyanoacetates, cyanoacetamides, ethoxy methylene malononitriles, ammonia, urea, .beta.-diketones, .beta.-ketoesters, malonates, alkylamidines and alkylsulfonylacetonitriles. Some literature techniques are illustrated below. Using these techniques or suitable modifications that would be apparent to one skilled in the art, the 2-aminopyridine and 4-aminopyrimidine intermediates can be readily prepared.
Condensation of ethoxyethylidenemalononitrile and acetamidine yields the corresponding 4-aminopyrimidine-5-carbonitrile as reported, Chem. Ber., 71, 87 (1938). ##STR12##
The following sequence of reactions is reported [J. Med. Chem., 24, 382 (1981)] to yield chloro and alkoxy substituted 4-aminopyrimidine-5-carbonitriles. ##STR13##
Treatment of methyl cyanoacetate with ethanolic hydrogen chloride affords the imidate which is condensed with acetylacetone as described [Chem. Ber., 73, 542 (1940)] to give the 2-aminopyridine-3-carboxylate. ##STR14##
Heterocyclic amines II in which W is a nitro group are prepared by nitration of the corresponding unsubstituted amine as is reported for 2-amino-4,5-dimethyl-3-nitropyridine, Rocz. Chem., 37, 385 (1963), [Chem. Abstr., 59, 11486 (1963)]. ##STR15##
Those intermediates of Formula II in which A is A-2, A-3 or A-4 may be readily prepared by known methods or modifications of these methods. Reference to the following publications is suggested for further details: Brit. Patent GB 1,057,612, U.S. Pat. No. 3,318,881, Belg. Patent BE 895995A, Japan.

Those intermediates of Formula II in which R is a methyl group may be readily prepared from the corresponding aminoheterocycles (R=H) by known methods for the monomethylation of heterocyclic amines; J. Chem. Soc. Perkin I, 1569 (1981).

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, 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.

Utility
Test results indicate that the compounds of the present invention are active herbicides. They appear to 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. In addition, test results indicate that certain compounds are useful for selective pre- and post-emergence weed control in sugar beets. Alternatively, the subject compounds are useful for plant growth modification.
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 herbicides, the 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 0.06 to 10 kg/ha, the lower rates being suggested for use as selective pre- and post-emergent herbicides in sugar beets, 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 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 and mefluidide.
The herbicidal and plant growth modifying 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), sicklepod (Cassia obtusifolia), morningglory (Ipomoea sp.), cocklebur (Xanthium pensylvanicum), sorghum, corn, soybean, sugar beet, rice, wheat, cotton, 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, 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 O=no injury, to 10=complete kill. The accompanying descriptive symbols have the following meanings:
C=chlorosis or necrosis;
D=defoliation;
E=emergence inhibition;
G=growth retardation;
H=formative effects;
U=unusual pigmentation;
X=axillary stimulation;
S=albinism; and
6Y=abscised buds or flowers.
The data indicate that at the low rates of application selected for these evaluations, most of the compounds tested are highly active herbicides. Additionally, they often possess plant growth modifying properties, such as causing growth retardation or axillary stimulation. ##STR45##

The following test was performed to better define the pre-emergence activity of the claimed compounds.
Test B
Two plastic bulb pans were filled with fertilized and limed Woodstown sandy loam soil. 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), 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. Results for several of the more active compounds are presented in Table B. Almost all of the compounds tested showed pre-emergence activity on a number of species at rates as low as 31 g/ha; some were active at even lower rates. At higher rates, e.g. 125 g/ha, most compounds exhibited broad spectrum pre-emergence activity.

The following test was performed to better define the post-emergence activity of the claimed compounds.
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 are sometimes added to this standard test in order to evaluate unusual selectivity.
Results for two of the most active compounds tested in this screen are presented in Table C. Many of the other compounds also showed post-emergence activity at rates as low as 4 or 16 g/ha.

Test D
Two 25-cm in diameter plastic pans lined with polyethylene liners were filled with prepared Sassafras loamy sand soil. One pan was planted with seeds of wheat (Triticum aestivum), barley (Hordeum vulgare), wild oats (Avena fatua), blackgrass (Alopecurus myosuroides), annual bluegrass (Poa annua), green foxtail (Setaria viridis) and Italian ryegrass (Lolium multiflorum). The other pan was planted with seeds of wild radish (Raphanus naphanistrum), kochia (Kochia scoparia), Matricaria inodora, black nightshade (Solanum nigrum), wild mustard (Brassica kaber), wild buckwheat (Polygonum convolvulus), Galium aparine, Veronica persica and sugar beets (Beta vulgaris). 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 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. All treatments were maintained in the greenhouse for 21 days at which time the treatments were compared to the controls and the effects visually rated utilizing the rating system as described in Test A. The recorded data are presented in Table D. The data indicate that the compound tested has utility for selective weed control in sugar beets.
