The presence of undesired vegetation causes substantial damage to useful crops, especially agricultural products that satisfy man's basic food needs, such as soybeans, barley, wheat, and the like. The current population explosion and concomitant world food shortage demand improvements in the efficiency of producing these crops. Prevention or minimizing the loss of a portion of 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 exists, however, for still more effective herbicides that destroy or retard weeds without causing significant damage to useful crops.

DETAILED DESCRIPTION OF THE INVENTION Synthesis The following discussion represents a general outline for the preparation of the compounds of this invention. All of the syntheses described below are multistep with one or more methods being taught for each step. This allows for a wide variety of possible synthetic pathways to prepare a particular compound of Formula I. The proper choice of the synthetic pathway and the best ordering of the reaction sequences for each individual compound will be known to one skilled in the art. The compounds of Formula I can be prepared by one or more of the methods described below in Equations 1 through 5. Reaction conditions are given by way of example only. As shown in Equation 1, many of the compounds of Formula I where J is J₁, J₂, J₃ and J₄, can be prepared by reacting a sulfonylisocyanate (W = 0) or, a sulfonylisothiocyanate (W = S) of Formula II with an appropriate heterocyclic amine of Formula III. R, A and W are as previously defined. Equation 1 The reaction is carried out at 25° to 100°C in an inert, aprotic solvent such as methylene chloride or xylene for 0.5 to 24 hours as taught in U.S. Patent 4,127,405. Many of the compounds of Formula I, where J is J₁, J₂, J₃ and J₄, W is S and R is H, (Ia) can be prepared by reacting the appropriate sulfonamide of Formula IV with a heterocyclic isothiocyanate of Formula V, as shown in Equation 2. Equation 2 The reaction is carried out at 25° to 80°C in an inert, aprotic solvent such as acetone or acetonitrile in the presence of a base such as potassium carbonate for 0.5 to 24 hours. The required heterocyclic isothiocyanates V are prepared from the corresponding amines III which would be known to one skilled in the art as taught in EPO Publication 35,893. Many of the compounds of Formula I, where J is J₁, J₂, J₃ and J₄ and W is O (Ib), can be prepared by reacting a sulfonylcarbamate of Formula VI with an appropriate amine of Formula III, as shown in Equation 3. Equation 3 The reaction is carried out at 50° to 100°C in a solvent such as dioxane for 0.5 to 24 hours. The required carbamates VII are prepared by reacting the corresponding sulfonamides IV with diphenylcarbonate in the presence of a strong base. Compounds of Formula Ib can also be prepared, as shown in Equation 4, by reacting a heterocyclic carbamate of Formula VII with an appropriate sulfonamide of Formula IV. Equation 4 The reaction is carried out at 0° to 50°C in a solvent such as acetonitrile or dioxane in the presence of a non-nucleophilic base such as DBU for 0.2 to 24 hours. The required phenylcarbamate VII are prepared by reacting the corresponding heterocyclic amines III with diphenylcarbonate or phenylchloroformate in the presence of a strong base. Many of the compounds of Formula Ib where J is J₁, J₂, J₃ and J₄ can be prepared by reacting the sulfonamides of Formula IV with an appropriate methylcarbamate of Formula VIII in the presence of an equimolar amount of trimethylaluminum, as shown in Equation 5. Equation 5 The reaction is carried out at 25° to 40°C in a solvent such as methylene chloride for 10 to 96 hours under on inert atmosphere. The required carbamates VIII are prepared by reacting the corresponding amines III with dimethylcarbonate or methyl chloroformate in the presence of a strong base. The intermediate sulfonylisocyanates (W = 0) and sulfonylisothiocyanates (W = S) of Formula II from Equation 1 can be prepared as shown in Equations 6 through 8. As shown in Equation 6, many of the sulfonylisocyanates of Formula IIa where J is J₁, J₂, J₃ and J₄ can be prepared by the reaction of sulfonamides of Formula IV with phosgene, in the presence of n -butylisocyanate and a tertiary amine catalyst, at reflux in a solvent such as xylene by the method of U.S. Patent 4,238,621. Equation 6 The sulfonylisocyanates can also be prepared from the sulfonamides by a two step procedure involving (a) reacting the sulfonamides with n -butylisocyanate in the presence of a base such as K₂CO₃ at reflux in an inert solvent such as 2-butanone forming a n -butylsulfonylurea; and (b) reacting this compound with phosgene and a tertiary amine catalyst at reflux in xylene solvent. The method is similar to a procedure taught by Ulrich and Sayigh, Newer Methods of Preparative Organic Chemistry, Vol. VI. p. 223-241, Academic Press, New York and London, W. Foerst Ed. Alternatively, as shown in Equation 7, many of the sulfonylisocyanates of Formula IIa where J is J₁, J₂, J₃ and J₄ can be prepared by reacting the corresponding sulfonyl chlorides IX with cyanic acid salts. Equation 7 The reaction is carried out at 25° to 100°C in an inert aprotic solvent such as acetonitrile for 0.5-24 hours in the presence of phosphorus pentoxide and an alkali metal salt such as lithium iodide. Many of the sulfonylisothiocyanates of Formula IIb where J is J₁, J₂, J₃ and J₄ can be prepared, as shown in Equation 8, by contacting the sulfonamides of Formula IV with carbon disulfide in the presence of two equivalents of a strong base. The resulting salt is then reacted with phosgene according to the teachings of K. Hartke, Arch. Pharm. , 299 , 174 (1966). Equation 8 The sulfonamides of Formula IV where J is J₁, J₂, J₃ and J₄ of Equations 2, 4, 5, 6 and 8 as well as the other sulfonamides required to prepare the compounds of this invention can be prepared from the corresponding sulfonyl chlorides of Formula IX by contacting with either anhydrous or aqueous ammonia as shown in Equation 9. Equation 9 The preparation of sulfonamides from sulfonyl chlorides is widely reported in the literature, for reviews see: F. Hawking and J. S. Lawrence, "The Sulfonamides," H. K. Lewis and Co., London, 1950 and E. H. Northey, "The Sulfonamides and Allied compounds," Reinhold Publishing Corp., New York, 1948. Alternatively, many sulfonamides IV can be prepared by dealkylation of their corresponding N- t -butyl sulfonamides X as shown in Equation 10. Equation 10 The reaction is carried out by contacting the N- t -butyl sulfonamide X with a strong acid such as trifluoroacetic acid or methanolic HCl at 25° to 50°C for 0.5 to 24 hours. The N- t -butyl sulfonamides X are readily prepared by reacting sulfonylchlorides IX with t -butylamine and are useful either as an aid in purification, to enhance solubility for subsequent reactions such as Equation 12 below or to protect the sulfonamide function from competing with reactions at other parts of the molecule. Many of the sulfonamides of Formula IVa can be prepared by functionalization of the corresponding N-unsubstituted sulfonamides of Formula IVb as shown in Equation 11. G₁-G₂ is CHR₃(CHR₄) n and CH=CR₄, R' is H or C(CH₃)₃ and X is Cl, Br, I or other readily displaceable groups. When R₃ is CH₃ then n is 0. Equation 11 The reaction is carried out by contacting the sulfonamides IVb with the appropriate electrophile in the presence of a suitable base such as K₂CO₃ in an inert, polar solvent such as DMF at 0° to 100°C for 0.5 to 24 hours. In some instances the R₂ function can also be introduced by Michael addition of IVb to the appropriate Michael acceptor as known to one skilled in the art. While many of the R₂ groups can be introduced directly, as described above, some of the R₂ groups may best be prepared by standard functional group manipulations upon compounds of Formula IVa containing an appropriate R₂ group pecursor as will be known to one skilled in the art. Some examples of these manipulations are the preparation of IVa where R₂ contains an epoxide by the epoxidation of IVa where R₂ contains a carbon-carbon double bond, the preparation of IVa where R₂ contains a sulfone by the oxidation of IVa where R₂ contains a thioether function, the preparation of IVa where R₂ contains OC(O)CH₃ by acetylation of IVa where R₂ contains OH, or the preparation of IVa where R₂ contains NH₂ by the reduction of IVa where R₂ contains NO₂. This is also the case for many of the R₁ substituents which can be prepared by an analogous chemical manipulation known to one skilled in the art. Many of the unsaturated sulfonamides of Formula IVc can also be prepared from the corresponding saturated sulfonamides of Formula IVd by the two-step procedure shown in Equation 12 . G₁-G₂ is SO₂-NR₂, CO-NR₅ or NR₅-CO, R' is H or C(CH₃)₃ and R'' is H or R₄. Equation 12 The first step involves benzylic bromination by N-bromosuccinimide to give a monobromide which is subsequently dehydrobrominated in a second step by reaction with a suitable base such as triethyl amine or potassium- t -butoxide in an inert solvent such as THF. This method has been used to prepare isocoumarins from 3,4-dihydroisocoumarins, see R. Barry, Chem. Rev. , 64, 229 (1964). In cases where R₁ is an alkyl group, competitive bromination at this site may occur resulting in a mixture. The desired bromide may be separated at this stage, or after treatment with the base, by standard methods. EP-A-107979 describes the synthesis of indanone and tetralone sulfamides which can be ketalized by standard methods known to one skilled in the art to give sulfonamides of Formula IV where J is J-11 and J-12. The sulfonyl chlorides of Formula IX of Equations 7 and 9 are important intermediates for the preparation of the compounds of this invention. The syntheses of the required sulfonyl chloride intermediates where J is J₁, J₂, J₃ and J₄ are described in Equations 14 through 16. As shown in Equation 14, many of the sulfonyl chlorides of Formula IX can be prepared from the corresponding amines XI. Equation 14 The reaction involves diazotization of the amine XI with sodium nitrite in HCl, followed by reaction of the diazonium salt with sulfur dioxide and cupric chloride in acetic acid analogous to the teachings of Yale and Sowinski, J. Org. Chem. , 25 , 1824 (1960). Alternatively, sulfonyl chlorides of Formula IX can be prepared by a modification of the above procedure whereby the diazotization reaction is carried out in dilute sulfuric acid and the resulting diazonium salt is reacted with sulfur dioxide, HCl and cupric chloride in a cosolvent mixture consisting of acetic acid-water (1:1) and an immiscible, inert solvent such as 1-chlorobutane or methylene chloride at 0°-40°C for 1 to 24 hours. Many of the sulfonyl chlorides of Formula IX can also be prepared by oxidative chlorination of the corresponding thio compounds of Formula XII as shown in Equation 15. R' is H, alkyl, benzyl or carbamoyl, R₁ is not SCH₃ and J does not contain non-aromatic unsaturation. Equation 15 The reaction is carried out by addition of molecular chlorine or a chlorine equivalent to the thio compound in the presence of water at 0° to 80°C in an aliphatic carboxylic acid solvent such as acetic acid or an inert organic solvent such as dichloroethane for 1 to 24 hours. Alternatively, many of the sulfonyl chlorides of Formula IX can be prepared by the two-step sequence shown in Equation 16 starting from the thio compounds XII where R' is H (XIIa) and R₁ is not SCH₃. Equation 16 The thiol XII (R'=H) is contacted with excess hydrogen peroxide in the presence of base to give a sulfonic acid salt which in turn is converted to the desired sulfonyl chloride by contacting with a suitable reagent such as thionyl chloride or phosphorous pentachloride as known to one skilled in the art. Some of the sulfonyl chlorides of Formula IX may best be prepared by direct chlorosulfonation depending on the substitution pattern on the ring and the nature of the substituent as will be known to one skilled in the art. Many of the S-arylthiocarbamates of Formula XIIb (XII, R'=CON(CH₃)₂) can be prepared by the Newman-Kwart rearrangement starting with the corresponding phenols XIII as shown in Equation 17. Equation 17 The phenol XIII is first reacted with N,N-dimethylthiocarbamoyl chloride in the presence of a base. The resulting O-aryl-N,N-dimethylthiocarbamate XIV is then heated at 150°C to 300°C for 2 to 24 hours as taught by Newman and Karnes J. Org. Chem. , 31 , 3980 (1966) to give the desired S-aryl-N,N-dimethylthiocarbamate XIIb. The related thiols XIIa can be obtained by hydrolysis of the thiocarbamates XIIb. Many of the sulfides of Formula XII where R' is alkyl or benzyl can be prepared by reacting a halocompound of Formula XV with an appropriate mercaptan in the presence of a base as shown in Equation 18. R' is alkyl or benzyl and X is F, Cl or Br. Equation 18 The reaction is carried out in a solvent such as DMF at 25° to 150°C for 0.5 to 24 hours. The halocompounds XV must not contain functionality which can be attacked by a mercaptide anion as will be known to one skilled in the art. An example of this would be where J is J₁ and R₂ was a haloalkyl group. These compounds can be prepared from the corresponding sulfides XII where J is J₁, R' is alkyl or benzyl and R₂ is H by standard alkylation methods. Many of the thiocompounds XII of Equation 15 and the chlorocompounds XV (X=Cl) of Equation 18, where J is J₁ and n is O, can be prepared by the reaction sequence shown in Equation 19. G is Cl or S-alkyl, R₁ does not contain functionality incompatible with BuLi or BH₃ and R₃ is as previously defined. Equation 19 The sequence begins by contacting an appropriately substituted N- t -butylbenzenesulfonamide XVI with two equivalents of butyl lithium at 0° to 25°C in an inert solvent such as THF for 2 to 10 hours to give a dianion according to the teachings of J. Lombardino, J. Org. Chem. , 36 , 1843 (1971). The dianion can then be trapped with an ester or, when R₃ is H, with dimethylformamide at -78° to 25°C to produce, upon aqueous acid workup, the hemiaminal XVII. The hemiaminal XVII can be de- t -butylated and dehydrated by a catalytic amount of acid such as p -toluene-sulfonic acid in a solvent such as benzene or toluene at reflux. The resulting benzisothiazole XVIII can be reduced with a reagent such as sodium borohydride in a suitable solvent such as ethanol to produce a 2,3-dihydrobenzisothiazole which is N-alkylated as described in equation II to give either XII (J=J₁, R'=alkyl) or XV (J=J₁, X=Cl) by standard methods known to one skilled in the art. Alternatively, hemiaminal XVII may be treated with diborane to produce a t -butyl-2,3-dihydrobenzisothiazole XVIIIa . Compounds XII (J=J₁, R'=alkyl) or XV (J=J₁, X=Cl) are then readily prepared as described previously by treatment of XVIIIa with trifluoroacetic acid followed by N-alkylation. If the t -butyl group in structures XVI and XVII is replaced by the appropriate R₂ group, the diborane reduction of the hemiaminal gives XII and XV directly. Many of the thio compounds XII of Equation 15 and the chloro compounds XV of Equation 18, where J is J₁ and J₄ and n=1, can be prepared by the reaction sequence shown in Equation 20. G is Cl or S-alkyl, Y is H or CH₃, R₁ does not contain functionality incompatible with BuLi. R'' is C(CH₃)₃ or functionality selected from R₂ which is compatible with the lithiation conditions shown as will be known to one skilled in the art and R₄ is H or C₁-C₄ alkyl. Equation 20 The reaction is carried out by reacting the N-substituted benzenesulfonamides XIX with two equivalents of n -BuLi at -780 to 250C in a solvent such as THF for 0.5 to 5 hours. When Y is H, an ortho-anion is formed which is trapped with an appropriate epoxide to give the hydroxy sulfonamides XX. When Y is CH , an ortho-methyl anion is produced which is reacted with an aldehyde or DMF to give alcohol XX. The alcohol can be mesylated by reaction of XX with mesyl chloride in the presence of an equivalent of a tertiary amine at 00 to 250C for 1 to 24 hours in a solvent such as methylene chloride. The resulting mesylate is cyclized by heating with a base such as potassium carbonate in a solvent such as DMF to produce the desired compounds XII (J=J±,JΔ, R'=alkyl) or XV (J=J±, JΔ, X=Cl). When R'' is C(CH ) , contacting with acid as described in Equation 10 will give the corresponding benzisothiazine where R'' is H. This can be alkylated as described previously for the benzisothiazoles of Equation 19. The amines of Formula XI in Equation 14, can be prepared by reduction of the corresponding nitro compounds of Formula XXI, as shown in Equation 22. Equation 22 The reduction of nitro compounds to amines can be carried out by any of several known methods as described in Preparative Organic Chemistry , 4 Ed., p. 557-563, John Wiley and Sons, New York and London, G. Hilgetag and A. Martini Ed. Many of the nitro compounds of Formula XXIII in Equation 22 can be prepared by the procedures outlined in Equations 23 through 30. With suitable modifications known to one skilled in the art, the general ring forming reactions outlined below for these nitro compounds XXIII can be adapted to prepare many of the phenols of Formula XIII and halocompounds of Formula XV. As shown in Equation 23, many of the nitro compounds of Formula XXI, where J is J₁ (XXIIIa) can be prepared starting from the appropriately substituted nitrobenzenes of Formula XXII. R' is H or CH₂Cl. Equation 23 The nitrobenzenes XXIV are first reduced to their corresponding amines and nitrated by standard methods to produce, in part, compounds of Formula XXV. In some instances, it may be desirable to first protect the amino group as its acetate prior to nitration as is known to one skilled in the art. The desired nitro compound XXV can be isolated by either fractional crystallization or chromatographic procedures and converted to sulfonyl chlorides XXVI by the method previously discussed in Equation 14. The intermediate sulfonyl chlorides XXVI can be converted into their corresponding sulfonamides by reaction with an appropriate amine (see Equation 9) and subsequently cyclized: a) when R' is CH₂Cl, to the nitro-1,2-benzothiazines XXIIIa, where n is 1, by heating in the presence of a base such as potassium carbonate; or b) when R' is H, by contacting the sulfonamide with NBS in a solvent such as carbon tetrachloride to give sulfonamides where R' is Br, followed by contacting this product with a base to give the nitro benzisothiazoles XXIa where n is 0. Note the discussion of Equation 12 for NBS brominations when R₁ is alkyl. The procedure of Equation 23 is similar to the method taught by E. Sianesi et al., Chem. Ber. , 104 , 1880 (1971) for the preparation of substituted 1,2-benzothiazine-1,1-dioxides. The starting nitrobenzenes XXII can be prepared by standard methods known to one skilled in the art. Alternatively, as shown in Equation 24, many of the nitro compounds of Formula XXIIIa where n is 1 can be prepared, in part, by contacting the nitro acetamides XXIII with fuming sulfuric acid according to the method taught by H. Zenno and T. Mizutani, ( Chem. Abst. : 72:79122 (1970)) for the preparation of 7-nitro-1,2-benzothiazine-1,1-dioxide. The resulting benzothiazines can be isolated and subsequently alkylated by standard methods known to one skilled in the art. Equation 24 Many of the nitro compounds of Formula XXIIIa where n is 0 can also be prepared from the corresponding 1,2-benzisothiazoles XXVI as shown in Equation 25. Equation 25 Nitration of XXVIII gives, in part, the 7-nitro derivative which is isolated by standard methods. The derivative is converted to its 1,1-dioxide by treatment with hydrogen peroxide. Reduction of the carbon-nitrogen double bond with NaBH₄ followed by alkylation of the resulting sulfonamide gives compounds XXIIIa where n is 0. The above reactions are characteristic of 1,2-benzisothiazoles XXVIII. For reviews of their synthesis and reactions, see L. L. Bambas, "The Chemistry of Heterocyclic Compounds," Vol. 4, part III, 1952, p. 223-378, and M. Davis. Adv. Heterocyclic Chem. , Vol. 14 (1972) p. 43-98. 1,2-Benzothiazines are also well known in the literature, for a review of their chemistry and alternate methods of their preparation see J. G. Lombardino, D. E. Kuhla, Adv. Heterocyclic Chem. , Vol. 28 (1981) p. 73-126. Many of the nitro compounds of Formula XXIII, where n=0 can also be prepared by reduction of the corresponding 3-nitrophthalic anhydrides with either sodium borohydride or lithium aluminum hydride in tetrahydrofuran as taught by M. Kayser and P. Morand, Can. J. Chem. , 58 , 2848 (1980) for the preparation of 7-nitrophthalide (XXIIId; n=0, R ' / 1=H). Phthalides and phthalic anhydrides are well known in the art, for a review of their synthesis and reactions see, S. Wawzonek, Heterocyclic Compounds , Vol. 2, John Wiley and Sons, Inc., New York, 1951. Many of the nitro compounds of Formula XXIII in Equation 22 where J is J₂ or J₃ can be prepared from the corresponding nitro compounds of Formula XXIII where J is J₁ (n=1) or J₄ respectively, by the bromination-dehydrobromination sequence described above for sulfonamides IV in Equation 12. The amines of Formula III in Equations 1 and 3 are also important intermediates for the preparation of the compounds of this invention and are described below. The pyrimidines and triazines of Formula (IIIa) to (IIId) below are either known or can be prepared by methods obvious to one skilled in the art. For a review of the synthesis and reactions of 2-aminopyrimidines (IIIa, Z=CR') see The Chemistry of Heterocyclic Compounds , Vol. 16 , John Wiley and Sons, New York (1962). For a review of the synthesis and reactions of 2-amino-s-triazines (IIIa, Z=N) see The Chemistry of Heterocyclic Compounds , Vol. 13 , John Wiley, New York (1959), F. C. Schaefer, U.S. Patent 3,154,547 and F. C. Schaefer and K. R. Huffman, J. Org. Chem. , 28 , 1812 (1963). The synthesis of the bicyclic amines IIIb and IIIc is taught in European Patent Application 15,683. The synthesis of bicyclic amines IIId is taught in European Patent Application 46,677. The synthesis of amines IIIa where X is cyclopropyl is taught in South African Patent Application 83/7434. The amines of Formula III where X is OCF₂H, OCH₂F, OCF₃ or CF₃; or X₁ is OCF₂H and/or Y is OCH₂F, OCF₃, SCH₂F, SCF₃ or GCF₂T wherein G is O or S and T is H, CHClF, CHBrF or CHFCF₃ can be prepared by methods that would be obvious to one skilled in the art. The pyrimidines of Formula IIIa (Z=CH) where Y is can be prepared according to the methods known to one skilled in the art. The triazine amines of Formula IIIe where X₃ is CH₃ or OCH₃ and R is H or CH₃ can be prepared according to the teachings of European Patent Application No. 94,260. Preparation of 3-amino-1,2,4-triazoles of Formula IIIf are known in the art and 1,2,4-triazoles are reviewed in The Chemistry of Heterocyclic Compounds "Triazoles 1,2,4" (John Wiley and Sons, New York, 1981). Commonly used starting materials containing nitrogen are N-aminoguanidine, hydrazine, alkylhydrazines, cyanamide, ethyl cyanoacetimidate, dimethyl cyanodithioimidocarbonate, dimethyl cyanoimidocarbonate, ethoxymethylenecyanamide, and acylhydrazines. Some literature syntheses are illustrated below. Using these techniques or suitable modifications that would be apparent to one skilled in the art, the 3-amino-1,2,4-triazole intermediates can be readily prepared. Heating equimolar amounts of ethyl propionimidate hydrochloride and N-aminoguanidine nitrate in pyridine gives 3-amino-5-ethyltriazole; German Patent 1,073,499 (1960); Berichte , 96 , 1064 (1963). Condensation of hydrazine with ethyl N-cyanoacetimidate yields 3-amino-5-methyltriazole; Journal of Organic Chemistry , 28 , 1816 (1963). U.S. Patent 2,835,581 (1958) teaches the preparation of 3-amino-5-(hydroxymethyl)triazole from N-aminoguanidine and glycolic acid. Condensing hydrazine with dimethyl cyanodithioimidocarbonate in acetonitrile gives 3-amino-5-methylthio-1,2,4-triazole while reaction of hydrazine with dimethyl N-cyanoimidocarbonate produces 3-amino-5-methoxy-1,2,4-triazole; Journal of Organic Chemistry , 39 , 1522 (1974). Reaction of substituted hydrazines with N-cyanothioimidocarbonates (prepared according to the procedure given in D. M. Wieland, Ph.D. Thesis, 1971, pp. 123-124) yields disubstituted aminotriazoles as shown below. Many of the aminoheterocyclic intermediates of Formula III where R is methyl may be prepared by a two-step procedure as described for IIIg in Equation 31, wherein X, Y and Z are as previously defined. Equation 31 A solution of the amine XXXVI in concentrated hydrochloric acid is treated with sodium nitrite solution and the chloro compound XXXVII is isolated in the usual manner by filtration of the acidic solution. A representative procedure is described by Bee and Rose in J. Chem. Soc. C , 2031 (1966), for the case in which Z = CH, and X = Y = OCH₃. Displacement of the chlorine of XXXVII may be accomplished by heating with an excess of methylamine in water to obtain the methylamino heterocycle (IIIg). Quaternization of amino functionality present in the R₂ group of compounds of formula I are also useful as herbicides and can be prepared by standard methods known to one skilled in the art. 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, 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 contacting 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.

IR (nujol) 1730, 1710, 1610 cm⁻¹. Using the procedures of Examples 1 to 7 and the methods described herein, the following compounds of Tables I-V can be prepared. 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 5% to 99% solid or liquid inert diluent(s). More specifically, they will contain these ingredients in the following approximate proportions: Weight Percent* Active Ingredient Diluent(s) Surfactant(s) Wettable Powders 20-90 0-74 1-10 Oil Suspensions, Emulsions, Solutions, (including Emulsifiable Concentrates) 5-50 40-95 0-15 Aqueous Suspension 10-50 40-84 1-20 Dusts 1-25 70-99 0-5 Granules and Pellets 1-95 5-99 0-15 High Strength Compositions 90-99 0-10 0-2 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°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. Preferably, ingredients should be approved by the U.S. Environmental Protection Agency for the use intended. 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. Patent 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 , December 4, 1967, pp. 147ff. and "Perry's Chemical Engineer's Handbook", 4th Ed., McGraw-Hill, New York, 1963, pp. 8-59ff.

Solutions of compounds of Formula I with J = J-5 to J-10 should be avoided due to the instability of the compounds when dissolved. 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, oil-well sites, drive-in theaters, around billboards, highway and railroad structures. Alternatively, the subject compounds are useful to modify plant growth. Certain of the compounds can be used to control weeds in crops such as wheat. The related compounds where J is J₁, n is O, R₁ = R₃=H and R₂ is isobutyl show excellent control of wild oats both pre- and postemergence and are also useful for preemergence and postemergence control of grassy weeds in broadlead crops such as cotton 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 5 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 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, sugarbeet, rice, wheat and purple nutsedge ( Cyperus rotundus ) tubers, and in certain cases, cotton 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 post-emergence with a soil/foliage application. At the time of treatment, the plants ranged in height from 2 to 19 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 or necrosis; E = emergence inhibition; G = growth retardation; H = formative effects; L = lodging; U = unusual pigmentation; X = axillary stimulation; and 6Y = abscised buds or flowers. The data show that most of the compounds tested are highly active herbicides with growth modifying properties and that some of the compounds tested provide selective weed control in crops such as wheat, cotton and soybeans. It will be noted that all compounds were tested at the low rate of 50 g/ha. Test B 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 ( Amena fatua ), cheatgrass ( Bromus secalinus ), blackgrass ( Alopecurus myosuroides ), annual bluegrass ( Poa annua ), green foxtail ( Setaria viridis ), rapeseed ( Brassica napus ),and Italian ryegrass ( Lolium multiflorum ). The other pan was planted with seeds of Russian thistle ( Salsola kali ), speedwell ( Veronica persica ), kochia ( Kochia scoparia ), shepherd's purse ( Capsella bursa - pastoris ), Matricaria inodora , black nightshade ( Solanum nigrum ), and wild buckwheat ( Polygonum convolvulus ). The above two pans were treated preemergence. At the same time two pans in which the above plant species were growing were treated postemergence. Plant height at the time of treatment ranged from 1-15 cm depending on plant species. The compounds applied were 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 20 days at which time the treatments were compared to the controls and the effects visually rated. The recorded data are presented in Table B.
