DETAILS OF THE INVENTION Compounds of Formula I are prepared by the methods shown below in Equations 1, 2, 3 and 4, wherein J, W, A and R are as previously defined. The method of choice for the individual compounds of Formula I will be readily apparent to those skilled in the art. Equation 1 illustrates the reaction of sulfonamides II with the phenol ester of the appropriate carbamie acid or thiocarbamic acid of Formula III in the presence of a tertiary amine base such as 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) . Similar coupling methods are described in EPA 70,804. Equation 1 a? DB J-S0 2 NH 2 + PhOCNR-A b) H 3 O η II III The reaction of Equation 1 is best carried out at about -5° to 25°C is an inert solvent such as dioxane or acetonitrile for 1 to 24 hours, optionally under an inert atmosphere and in the presence of an equimolar quantity of DBU. • The desired products of Formula I can be conveniently isolated by acidifying the reaction solution with aqueous hydrochloric acid or acetic acid and filtration. Alternatively, the aqueous layer can be extracted with a solvent such as methylene chloride. Drying and evaporating the solvent affords the desired product. The phenylcarbamate and phenylthiocarbamate intermediates of Formula III can be prepared by methods, or obvious modifications thereof, described in South African Patent Application 82/5671 and South African Patent Application 82/5045. Equation 2 illustrates the reaction of sulfonylisocyanates and sulfonylisothiocyanates of Formula IV with the appropriate heterocyclic amines of Formula V. Equation 2 J-S0 2 NCW + HNR-A ^ I IV V The reaction of Equation 2 is best carried out in an inert solvent such as methylene chloride, tetrahydrofuran, toluene or acetonitrile at a temperature between about 0° and 80°C. A catalytic amount of 1,4-diazabicyclo[2.2.2]octane (DABCO) can be used to accelerate the reaction. In cases where the products are insoluble in the reaction solvent, they can be isolated by simple filtration. Soluble products can be isolated by evaporation of the solvent and trituration of the residue with solvents such as 1-chlorobutane, diethyl ether or ethyl acetate, and filtration. Sulfonyl isocyanates IV (W=0) can be prepared directly from the corresponding sulfonamides II according to the procedures described in Ulrich et al., Newer Methods of Preparative Organic Chemistry, Vol. VI, page 223 to 241, Academic Press, New York and London, W. Foerst Ed. By this two-step procedure, sulfonamides are converted to isolatable n-butylsulfonylureas which are reacted further with phosgene and a tertiary amine catalyst to form sulfonyl isocyanates. The analogous one-step procedure can be employed by using the method described in U.S. Patent 4,238,621. Alternatively, sulfonamides can be reacted with thionyl chloride to form intermediate N-sulfinylsulfonamides, which upon exposure to phosgene in the presence of a catalytic amount of pyridine, provide sulfonyl isocyanates. For additional details, see Ulrich et al., J. Pro. Chem. , 34. pages 3200 to 3202 (1969). Sulfonyl isothiocyanates (iv, w=s) are prepared from the corresponding sulfonamides by reaction with carbon disulfide and potassium hydroxide followed by treatment of the resulting dipotassium salt with phosgene. Such a procedure is described in Arch. Pharm.. 299. 174 (1966). Equation 3 illustrates the reaction of a sulfonyl carbamate or thiocarbamate of Formula VI with an appropriate heterocyclic amine V. Equation 3 J-S0 2 NHC0C 6 H 5 + HNR-A YI V The reaction of Equation 3 is carried out at about 20° to 100°C in an inert solvent such as p-dioxane for 0.5 to 24 hours. Additional details concerning the general coupling reaction to prepare sulfonylureas can be found in EPA 44,807. The product is isolated by evaporation of the reaction solvent and purified by trituration of the residue with solvents such as 1-chlorobutane or ethyl ether, and filtration, or by chromatography procedures on silica gel. Phenylcarbamates and phenylthiocarbamates of Formula VI are prepared by methods described, or obvious modifications thereof, in U.S. Patent 4,443,243, EPA 44,808 or South African Patent Application 82/5042. Equation 4 illustrates the reaction of sulfonamides of Formula Ia with appropriate salts or amines to form corresponding sulfonamides of Formula lb. Equation 4 la. Ih wherein P is S0 2 NHCNR-A; A, Alk, R and R, are as previously defined; M is Na + or K + ; Ta is CN, SCN, N_, C χ to C 3 alkoxy, C χ to C 2 thioalkyl, or F; Tb is NH(C χ to C 2 alkyl), N(C χ to C 2 alkyl) 2 , N(OCH 3 )CH 3 , or I(( H 2 ) 3 or 4 ; and Tc is Ta or Tb. The reaction of Equation 4 is effected by reacting Ia with at least one molar equivalent of salt M-Ta (at least two molar equivalents when Ta is an alkoxide or mercaptide) in an inert solvent such as acetone, methyl ethyl ketone, tetrahydrofuran, dioxane, methanol, dimethylformamide (DMF) , dimethylsulfone or dimethylsulfoxide. The reaction is carried out at about 20° to 140°C for 1 to 24 hours, and optionally in the presence of a phase transfer catalyst such as a crown ether. Products lb (Tc is Ta) are isolated by addition of water, acidification if Ta is alkoxide or mercaptide, and filtration. Alternatively, the aqueous suspension is extracted with a solvent such as methylene chloride, dried and the solvent evaporated to yield crude lb. Product lb can be purified further by trituration with a solvent such as 1-chlorobutane, ethyl acetate or diethyl ether, and filtration, or by chromatography procedures on silica gel. Similarly, products lb (Tc is Tb) can be prepared by reacting Ia with amines, H-Tb, preferably an excess of about 2 to 20 mole equivalents, in an inert solvent such as tetrahydrofuran, p-dioxane, methanol, methylene chloride or DMF. The reactions are carried out at about 0°C to 100°C for 1 to.24 hours. Work-up is as described above. In anlogous manner, other compounds of Formula I can be prepared using procedures described in Equation 4, from appropriate corresponding compounds of Formula I, wherein J is J 2 to and Q 1 or Q 2 is C(Cl)=NOAlk. As illustrated in Equation 5, the intermediate sulfonamides of Formula II are conveniently prepared by amination of the corresponding sulfonyl chlorides with anhydrous ammonia or aqueous ammonium hydroxide by general methods known in the art, e.g., Crossley et al., J. Am. Chem. Soc.. 60. pages 2223 to 2224 (1938); Pailer, Monatsh. 92, pages 677 to 683 (1961); and U.S. Patent 4,511,392. Equation 5 NH - J-S0 2 C1 or NH 4 OH J-S0 2 NH 2 VII II As illustrated in Equation 6, sulfonamides of Formula II can also be prepared by deprotection of i-butylsulfonamides of Formula VIII. Equation 6 TFA, PPA v, J-S0 2 NH-C(CH 3 ) 3 or p-TSA J-S0 2 NH 2 VIII II The reaction of Equation 6 is conveniently carried out in excess trifluoroacetic acid (TFA) according to the procedure of Catt et al., J. Or . Chem.. 39. pages 566 to 568 (1974), or with polyphosphorie acid (PPA) according to procedures of Lomardino, J. Orq. Chem.. 36, pages 1843 to 1845 (1971). Alternatively, i-butylsulfonamide VIII can be treated with a catalytic amount of p-toluene sulfonic acid (p-TSA) in a solvent such as toluene or xylenes at reflux temperatures for 1 to 24 hours to yield II * . Intermediate sulfonyl chlorides of Formula Vila are preferably prepared by oxidative-ehlorination of an appropriate thioether of . Formula IX, as shown below in Equation 7. Equation 7 Cl-, H-O 2 —-2 > J-SR CH 3 C0 2 H or CH 3 CH 2 C0 2 H J-S0 2 C1 IX Vila wherein J is as previously defined, E is a single bond, and R is C 2 to C 3 alkyl or benzyl. The reaction of Equation 7 is carried out by contacting a suspension of thioether IX in a solvent such as acetic or propionic acid in the presence of at least 2.5 equivalents of water and 3.0 equivalents of chlorine at about -20° to 30°C for 0.2 to 5 hours. The reaction mixture is poured into ice-water and the product is isolated by filtration or extraction with a solvent such as methylene chloride. The extraction product is optionally washed with aqueous sodium bicarbonate until neutral or slightly basic to litmus, then dried, and the solvent is evaporated to yield a product sufficiently pure to be carried directly on to the next step. Alternatively, reaction of thioether IX, wherein R 4 is benzyl or hydrogen, with a hypochlorite solution, i.e., NaOCl, can provide sulfonyl chloride ^ Vila. For additional details, see analogous reactions in South African Patent Application No. 84/8845 and 84/8844. Mercaptans or thioethers can also be transformed to sulfonyl fluorides by reaction with chlorine and potassium hydrogen difluoride, which on further reaction with ammonia or ammonium hydroxide can provide sulfonamides; see, e.g.. Brown et al., J. Chem. Soc. Perkins Trans I. pages 522 to 527 (1972). Sulfonyl chlorides, Vila, can also be prepared by diazotization reactions, as illustrated in Equation 8.

Doyle, J. Orq. Chem.. 42, pages 2426 to 2431 (1977) and ibid, pages 2431 to 2436, describe conditions for analogous reactions. Alternatively, sulfonyl chlorides Vila can be prepared by aqueous diazotization; for additional details, see EPA 83,975 and 85,476. Aromatic amines of Formual X can be prepared from the corresponding nitro compounds by various known reduction procedures, e.g., Preparative Organic Chemistry. 4 Ed. , pages 557 to 563, John Wiley and Sons, New York and London, Hilgetag et al., Eds., and EPA 207,894. Sulfonyl chlorides of Formula Vllb can be prepared from compounds of Formula XI as shown in Equation 9 and described in U.S. Patent 4,420,325. wherein J is as previously defined and [X] is a suitable halogenating agent, such as N-bromosuccinimide. Thioethers of Formula IX are important intermediates for preparing compounds of this invention and can be prepared by a variety of general methods known in the art. Several such procedures are described below in Equations 10 through 15. Equation 10 illustrates the preparation of thioethers of Formula IXa, containing an alpha-chlorooxime moiety, from carboxylic acids of Formula XII. Subsequent reaction of IXa with appropriate salts, M-Ta, or amines, H-Tb, provides thioethers of Formula IXb. Equation 10 k (Br) XII I∑ I∑ wherein R j , R 4 , Alk, M, Ta, Tb and Tc are as previously defined; and [X] is as defined below.. In Equation 10a, carboxylic acids XII are converted to acid chlorides which in turn are converted to isolatable N-alkoxyamides by known methods. Subsequent reaction of the amides with suitable halogenating agents, [X], provides compounds of Formula IXa. Suitable halogenating agents include phosphorous pentachloride or phosphorous pentabromide in an inert solvent such as benzene or chloroform at about 5° to 40°C for 1 to 24 hours; or phosgene, preferably, or thionyl chloride and a catalytic amount of DMF in an inert solvent such as methylene chloride, benzene or chlorobenzene at about 10° to 130°C for 0.5 to 24 hours; or more preferably equimolar amounts of triphenylphosphine and carbon tetraehloride (or carbon tetrabromide) in an inert solvent such as acetonitrile at about 0°C to 80°C for 1 to 24 hours. Compounds of Formula IXa are isolated by evaporation of reaction media under vacuum and can be purified by optionally treatment with water followed by chromatography procedures on silica gel. The reactions of Equation 10b are carried out by the general procedures described in Equation 4.

Suitable bases and solvents include potassium tert-butoxide in DMF or sodium methoxide in ethanol. Reactions 4) and 5) of Equation 11 are further illustrated in Example 7. In an analogous manner to reactions described in Equations 10 and 11, other thioethers of Formula IX can be prepared, wherein J is J 2 to J13 by carrying out reactions on appropriate corresponding carboxylic acids or aldehydes. Equation 12 illustrates the preparation of aldooxi es and ketooximes of Formula IXd.

In Equation 12b, reaction of halopyridine XV with an appropriate mercaptide in a solvent such as DMF yields the corresponding thioethers, which on reaction with an alkoxyamine by known methods yields compounds of Formula IXd. U.S. Patent 4,456,469 discloses analogous halopyridine-mercaptide reactions. Also, by known methods, aldo or keto-thioethers in Equation 12b can be reacted with hydroxylamine followed by a suitable base and an alkylating reagent, M-Alk, to provide capped oximes Ixd.

Salvador et al., J. Med. Chem. , 15, pages 646 to 650 (1972). Oximes of Formula IXd, wherein Te' is CH 2 CN, can be prepared in a two-step procedure from an appropriate 2-benzylthio-3-pyridyl-carboxylate ester 5 using generally known methods. Thus, reaction of the ester with a suitable base such as sodium hydride and acetonitrile in an inert solvent such as tetrahydrofuran can provide the corresponding 3-ketoacetonitrile, which on subsequent reaction with 0) an appropriate alkoxyamine, or more preferably, its hydrochloride salt, in an inert solvent such as methanol or DMF can provide IXd (Te* is CH 2 CN) . Pyridyl alkyl ketones described in Equations 12a and 12b can also be prepared by reaction of 5 appropriate pyridyl acid chlorides with alkyl Grignard reagents. For details see, for example, Japanese Patent Application 60-253,531.

For further details pertaining to the synthesis of pyrazoles see, for example, EPA 87,780; South African Patent Application 833,350, EPA 95,925; and Jacobs, "Heterocycloc Compounds", Elderfield ed., Vol. 5, pages 45 to 161, Wiley, New York, 1957. Chemical compatibility of the wide variety of reactions, reactants and reaction conditions described throughout this disclosure with respect to J, R^ to R 3 , Q^ and Q 2 must be evaluated and judicious choices made; one skilled in the art, having this disclosure before him, will be able to readily make such evaluations and choices without undue difficulty. In addition, incompatibility can readily be avoided in certain instances by suitable selection of a protecting group as will be obvious to one skilled in the art. For a compilation.of references describing the wide variety of such protecting groups available, see Greene et al., "Protective Groups in Organic Synthesis", John Wiley and Sons, Inc., New York, 1981. The heterocyclic amines of Formula V in Equation 2 above can be prepared by methods known in the literature, or simple modifications thereof, by those skilled in the art. For instance, EPA 84,224 and Braker et al., J. Chem. Soc, 69, 3072 (1947), describe methods for preparing aminopyridines and triazines substituted by acetal groups such as dialkoxymethyl or l,3-dioxolan-2-yl, among other groups. Also, South African Patent Application Nos. 82/5045 and 82/5671 describe methods for preparing aminopyrimidines and triazines substituted by haloalkyl or haloalkylthio groups such as OCH 2 CH 2 F, OCH 2 CF 3 , SCF 2 H, and OCF 2 H. South African Patent Application 83/7434 describes methods for the synthesis of cyclopropylpyrimidines and triazines substituted by such groups as alkyl, haloalkyl, alkoxy, haloalkoxy, " alkylamino, dialkylamino or alkoxyalkyl. The 5,6-dihydrofuro[2,3-d]pyrimidine-2- amines, the cyclopenta[d]pyrimidines-2-amines (V, A is A-2) and the 6,7-dihydro-5H-pyrano[2,3-d]pyrimidin-2- amines (V, A is A-3) can be prepared as described in EPA 15,683. The furo[2,3-d]pyrimidin-2-amines (V, A is A-4) are described in EPA 46,677. Compounds of Formula V, where A is A-7, are described in EPA 125,864. Compounds of Formula V, where A is A-5, are described in EPA 73,562. Compounds of Formula V where A is A-6, are described in EPA 94,260. In addition, general methods for preparing aminopyrimidines and triazines have been reviewed in the following publications: "The Chemistry of Heterocyclic Compounds", a series published by Interscience Publ., New York and London; "Pyrimidines", Vol. 16 of the same series by Brown; "^.-Triazines and Derivatives", Vol. 13 of the same series by Smolin et al.; U.S. Patent 3,154,547; and Huffman et al., J. Orq. Chem.. 28, pages 1812 to 1816 (1963), which describes the synthesis of triazines. 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 compounds of Formula I with a solution of an alkali or alkaline earth metal salt having a sufficiently basic anion (e.g., hydroxide, alkoxide, or carbonate). 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 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 and can be separated by filtration. Exchange can 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 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 specific examples. Unless otherwise indicated, temperatures are in degrees Celsius.

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 as spray volumes of from a few liters to several hundred liters per hectare. High strength compositions are primarily useadi 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 these carriers: (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: eiσht Percent* Active 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) * 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 5 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 10 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 15 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°C. "McCutcheon's Detergents and 20 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 25 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 30 blending and, usually, grinding as in a hammer or __ * fluid energy mill. Suspensions are prepared by wet milling (see, for example. Littler, U.S. Patent ~ 3,060,084). Granules and pellets may be made by _ spraying the active material upon preformed granular 35 carriers or by agglomeration techniques. See J. E. Browning, "Agglomeration", Chemical Engineering. December 4, 1967, pages 147ff. and "Perry's Chemical Engineer's Handbook", 5th Ed., McGraw-Hill, New York, 1963, pages 8-57ff.

Utility Test results indicate 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 postemergence weed control in areas where complete control of all vegetation is desired, such as around storage tanks, 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 rice, wheat, barley, corn, sorghum, soybeans and cotton. 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 5 to 20 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 persistence is required, such as a herbicide for fallow land. 10 The compounds of the invention may be used in combination with any other commercial herbicide, representative examples of which are those of the sulfonylurea, triazine, triazole, uracil, urea, amide, diphenyl ether, carbamate, imidazolinone, cineole and 15 bipyridylium types.

Japonica and Indica rice seedlings at the 2.0 to 2.5 leaf stage were transplanted into 1/3 of the pots. Into another third of the pots were transplanted seedling or sprouted tubers of water plantain (Alisma trivale) , Scripus (Scirpus paludosus) , Cyperus (Cyperus esculentus) . and arrowhead (Sagittaria spp.). The remaining pots were planted with barnyardgrass (Echinochloa crus-galli) seeds and sprouted tubers of water chestnut (Eleocharis spp.). These weeds all represent major rice weeds or genera of weeds important in rice. Three to four days after planting, the water level was raised to 3 cm (about 1200 ml/pot) and maintained at this level throughout _ the test. Chemical treatments were applied directly to the paddy water, within 24 hours of raising the water, after being formulated in a nonphytotoxic solvent. The pots were maintained in the greenhouse.

Alterntively, for postemergence tests, plants were grown in a 50:50 mixture of commercially available potting mix and Sassafras soil. Plantings for the 10 preemergence phase were made in a Tama silt loam soil (approximately 3% organic matter) the day before, or the day of treatment. Approximate planting depths were corn and soybeans - 3 to 4 cm; morningglory, cocklebur, and nutsedge - 2.5 to 3 cm; velvetleaf, 15 sicklepot, and sesbania - 2 cm; all other species - 0.5 c . The test chemicals were dissolved/suspended in a nonphytotoxic solvent in concentrations required to obtain the desired rate of application. The 20 solutions or suspensions were then applied as soil/foliage sprays to the young plants (postemergence phase) and to the soil surfaces of the freshly planted containers (preemergence phase) . Application was made utilizing an automatic spray 25 machine at a spray volume of 374 liters per hectare. Immediately after treatment, the containers were transferred to a greenhouse and subsequently watered on a demand basis, taking care not to wet the foliage of the plants in the postemergence phase of the test. 30 The following species were included in the test: » 35 258 APPROXIMATE GROWTH STAGE AT POST PLANT SPECIES SCIENTIFIC NAME APPLICATION Grass Weeds: Barnyardgrass Echinochloa crus-galli Giant foxtail Setaria faberi Green foxtail Setaris viridis Johnsongrass Sorghum halepense Fall panicum Panicum dichotomiflorum Purple nutsedge Cyperus rotundus Signalgrass Brachiaria platyphylla Crabgrass Djgitaria sanguinalis Velvetleaf Abutilon theophrasti JFiimsonweed Datura stramonium Hemp sesbania Sesbania exaltata Sicklepod Cassia obtusifolia Cocklebur Xanthium pensylvanicum Ivyleaf morningglory Ipomoea hederacea 1-2 true leaves Ladysthumb smartweed Polygonum persicaria 3-4 leaves Pigweed Amaranthus retroflexus 4-5 leaves Lambsquarters Chenopodium album 4-5 leaves Teaweed Sida spinosa 2-3 leaves Eastern black- Solanum ptycanthum 2nd true leaf nightshade Corn (Funk Zea mays 2-3 leaves G4646) Soybeans Glycine max 1st trifoliate (Williams) Visual plant response ratings were made approximately two and four weeks after treatment for the post- and pre-emergence phases, respectively.
