Description: TITLE CYCLIC SULFONAMIDE HERBICIDES BACKGROUND OF THE INVENTION This invention relates to certain cyclic sulfonamides, their agriculturally-suitable salts and compositions, and methods of their use as general or selective preemergent or postemergent herbicides. 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, citrus and soybeans, to name a few. Unchecked weed growth in such crops (including plantation 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 railroad tracks, storage tanks and industrial storage areas. There are many products commercially available for these purposes, but the search continues for products which are more effective, less costly and environmentally safe.

The invention further comprises anilines of Formula 1 and 2 wherein R 1 , R 2 , R 3 , R 4 , R 5 and X are as defined for compounds of Formula I and II above. The anilines are intermediates in the preparation of compounds of Formula I and II. DETAILS OF THE INVENTION The compounds of Formulae I and II can be prepared by one or more of the following methods, or variations obvious to one skilled in the art, as described below in Schemes 1-21. The definitions of Z, Z 1 , Q, Q 1 , X, W, n, m, and Rl through R 26 in the compounds of Formulae 1-46 below are as defined above in the Summary of the Invention. Compounds of Formulae Ia-Ir are various subsets of the compounds of Formula I, and all substituents for Formulae Ia-Ir are as defined above for Formula I. Compounds of Formulae I and II are prepared from the corresponding anilines of Formulae 1 and 2, respectively, as represented in Scheme 1. Scheme 1 π Synthesis of Anilines of Formulae 1 and 2 Anilines of Formulae 1 and 2 wherein X is a direct bond (Formula 2a) are prepared by the method illustrated in Scheme 2. The nitro aniline of Formula 3 is treated with a sulfonyl chloride in the presence of a base such as pyridine, N,N-dimethylaminopyridine (DMAP), or triethylamine at -20° to 25°C to obtain the sulfonamide of Formula 4. For compounds wherein R 3 is other than H, the sulfonamide nitrogen can be alkylated or acylated to give the R 3 -substituted compound of Formula 5. The alkylation is performed using an alkyl halide or alkyl sulfonate in the presence of a base such as potassium carbonate, sodium methoxide, potassium r-butoxide (t-BuOK), or sodium hydride in an anhydrous solvent such as dimethylformamide (DMF), tetrahydrofuran, or acetonitrile at ambient temperature to 80°C. Acylations to form the R 3 = C(O)R 6 compounds are accomplished by condensing the sulfonamide of Formula 4 with the appropriate acylating agent, for example an acyl chloride, isocyanate or carbamoyl chloride. Scheme 2 Lg = α, Br, OS(0) 2 (4-Me-Ph), G=Br, I, OS(0)2(4-Me-Ph), OS(02CH 3 OS(0)2CH 3 la 2a The cyclization to form the cyclic sulfonamide functionality is achieved via intramolecular vicarious nucleophilic substitution of hydrogen as described by K. Wojciechowski and M. Makosza in Synthesis, (1992), 571. Treatment of the sulfonamide of Formula 5 with a base such as sodium hydroxide, sodium methoxide, or potassium t-butoxide in an inert solvent such as dimethyl sulfoxide (Me 2 SO), dimethylformamide or tetrahydrofuran at a temperature between -60°C and ambient temperature affords the cyclic sulfonamides of Formulae 6 and 7. The ratio of products depends on the nature of R 2 , and the base and solvent used in the cyclization. If R 2 is other than hydrogen, only compounds of Formula 6 are obtained. When R 2 is hydrogen and a mixture of products is obtained, the isomers can be separated by chromatography or crystallization techniques. The nitro group in the compounds of Formulae 6 and 7 can be reduced to the corresponding anilines of Formula 1 and 2a, respectively, using iron-HCl, SnCl 2 Η 2 O, or hydrogen over palladium on carbon. In some instances, it may be desirable to introduce a non-hydrogen R 2 group in anilines of Formula 1 after cyclization. For example, introduction of a chlorine or bromine atom to give anilines of Formula la can be accomplished using N-chlorosuccinimide (ΝCS) or N-bromosuccinimide (ΝBS), respectively, in an inert solvent such as dimethylformamide (DMF) at a temperature between ambient temperature and 80°C. The nitro compounds of Formula 3 are prepared as illustrated in Scheme 3. The amino group of the aniline of Formula 8 is protected with a suitable protecting group, for example as the phthalimide by reaction with phthalic anhydride, to give the protected aniline of Formula 9. For suitable amino protecting groups, see T. W. Greene and P. G. M. Wuts, Protective Groups in Organic Synthesis, 2nd Edition, John Wiley and Sons, Inc., New York, (1991). Nitration of 9 using a nitric acid/sulfuric acid mixture at -20° to 20°C affords the nitro compound of Formula 10. Deprotection of the amino group (using hydrazine in the case of the phthalimide group) affords the nitroaniline of Formula 3. The anilines of Formula 8 are known or can be prepared by well-known methods (see March, J., Advanced Organic Chemistry, (1992), 4th Ed., John Wiley and Sons, Inc., pp 591, 1103-1105). Anilines of Formulae 1 and 2a can also be prepared by introduction of the nitro group further along in the synthetic pathway as illustrated in Scheme 4. Scheme 4 Lg = Cl, Br, OS(0) 2 (4-Me-Ph) > 11 G= Br, I, OS(0) 2 (4-Me-Ph), OS(0) 2 CH 3 OS(0) 2 CH 3 2a The aniline of Formula 8 is contacted with a sulfonyl chloride as described above to give the sulfonamide of Formula 11. N- Acylation with an acyl chloride or the like, or N-alkylation with an R 3 -halide or -sulfonate in the presence of a base, as described above provides the N-substituted sulfonamide of Formula 12. Nitration to form the nitro compound of Formula 13 can be achieved using a nitric acid/sulfuric acid mixture at -20° to 20°C. Vicarious intramolecular nucleophilic substitution followed by reduction of the nitro group using the conditions described previously affords the anilines of Formulae 1 and 2a. Anilines of Formula 2 wherein X is other than a direct bond (Formula 2b) can be prepared starting from the corresponding amino phenol (X=O), amino thiophenol (X=S), or diamine (X=NH or N(C ] -C 3 alkyl)) of Formula 14 as illustrated in Scheme 5. Using conditions described above, the aniline is treated with a sulfonyl chloride to give the sulfonamide of Formula 15. Subsequent treatment with a base, for example potassium carbonate, induces cyclization. Nitration with nitric and sulfuric acid affords the corresponding nitro compound of Formula 16. N- Alkylation or N- acylation to introduce R 3 followed by reduction of the nitro group using the reaction conditions described above gives the aniline of Formula 2b. Scheme 5 N(C C 3 alkyl) 15 14 16 2b A similar but alternative method for the preparation of anilines of Formula 2b is outlined in Scheme 6. Starting with the nitro compound of Formula 17, the phenol (X=O), thiol (X=S), or amino (X=NH or N(C*|-C 3 alkyl)) group is protected with a suitable protecting group (see T. W. Greene and P. G. M. Wuts, Protective Groups in Organic Synthesis, 2nd Edition, John Wiley and Sons, Inc., New York, (1991)). For example, a benzyl (Bn) group is a particularly suitable protecting group and is introduced by treatment with benzyl bromide (BnBr) in the presence of K 2 CO 3 . Reduction of the nitro group, for example with iron and HC1 as described above, affords the aniline of Formula 18. Condensation with a sulfonyl chloride followed by N-alkylation or N-acylation affords the N-substituted sulfonamide of Formula 19. Scheme 6 17 18 19 2b Removal of the protecting group under the appropriate conditions (for example, by treatment with hydrogen over palladium on carbon in the case of an OBn group) and treatment with base induces cyclization to form the cyclic sulfonamide. Nitration and reduction as described above affords the aniline of Formula 2b. Converting Anilines of Formulae 1 and 2 to Compounds of Formulae I and II The anilines prepared by the methods outlined in Schemes 1-6 are used in the condensation with J group derivatives to form compounds of Formulae I and II. In some instances, the anilines are used directly in the condensation reactions. In other instances and depending on the nature of the J-group, the NH 2 of the aniline is first converted to another functional group prior to condensation. For example, the aniline may be converted first to a hydrazine, an isocyanate or an aryl iodide. These methods are described in more detail below. Direct Coupling with the Anilines In some instances where the aniline is used directly, the compounds of Formulae I and II are prepared by condensation of the aniline with an anhydride precursor to the J group. For example, as illustrated in Scheme 7, the anhydride of Formula 20 is condensed with the aniline of Formula 1 to give compounds of Formula la wherein J = J- 1. This method is disclosed in EP-A- 170, 191. Scheme 7 20 la The anhydride of Formula 20 can be prepared by methods disclosed in EP 493,721, and WO 91/06216. Compounds of Formulae I and II wherein J = J-l 1 and J-l 8 can be prepared using similar methodology. The aniline is condensed with the appropriate J-group anhydride, diester, or other bis-electrophile to form the compound of Formula I or II. The synthesis of the J-l 1 precursor and the condensation reaction is described in EP 454,444 and EP 415,642. The J-18 group anhydride and the aniline condensation reaction are described in U.S. 4,003,926. The sulfonamides of Formulae I and II wherein J = J-10 are also prepared directly from the anilines of Formula 1 and 2, respectively. The J-10 group precursor and the aniline condensation reaction are described in WO 94/03459. Hydrazines For some compounds of Formulae I and π, the appropriate aniline is first converted to the corresponding hydrazine, and then the hydrazine is condensed with the J-group derivative, or precursor thereof, to form the desired material. The conversion of an aniline of Formula 1 to a hydrazine of Formula 21 is illustrated in Scheme 8. Subsequent condensation of the hydrazine with the iminoether precursor to J-2 followed by cyclization with phosgene forms the cyclic sulfonamide of Formula lb. The preparation of the iminoether J-2 precursor and the condensation procedure is described in U.S. 4,315,767. Scheme 8 21 lb Anilines can be converted to the hydrazines by diazotization and then reduction as is well-known in the literature (for example, see U.S. 4,695,312). Compounds of Formulae I and II wherein J = J-3 and J-8 are also prepared by first converting the aniline to the appropriate hydrazine, and then condensation with the appropriate J-group precursor. Methods for the preparation of the J-3 precursor and the condensation are described in U.S. 5,215,958, WO 90/02120, and U.S. 4,818,275. Methods for the preparation of the J-8 precursor and the condensation with a hydrazine are described in WO 92/12139 and U.S. 4,560,752. For some compounds of Formulae I and II wherein J = J-2 and Z is CR 9 Rl°, the synthesis is carried out as illustrated below in Schemes 9-17. The retrosynthetic analysis for the synthesis of the J-2 group is shown below (Scheme 9). The formation of ring A can be accomplished by intramolecular cyclization between the nitrogen in ring B and the terminal double bond of the triazolinone with the cyclic sulfonamide group already in place. J-2 m= 1 or2 The synthesis of the triazolinone ring B is known in the art and can be prepared by methods such as those described in U.S. 4,818,275 and U.S. 4,818,276. Acidic condensation of α-ketoacids of Formula 22 and a substituted phenyl hydrazine such as that of Formula 23 gives hydrazones of Formula 24. This reaction is performed under acidic conditions using hydrochloric acid in an organic solvent such as ethyl or methyl alcohol at a temperature between room temperature and about 100°C. Schmidt rearrangement of the acid of Formula 24 with diphenylphosphoryl azide between about 0°C and about 100°C followed by a ring cyclization gives the triazolinones as shown below (Scheme 10). The same conditions can be used to form the precursors to compounds of Formula II except the substituted phenyl hydrazine would contain the other cyclic sulfonamide functionality. Scheme 10 23 of Formula 23 For the synthesis of the triazolinones wherein Rl° is H, 2-oxo-5-hexenoic acid of Formula 22a can be used as the starting material. 2-Oxo-5-hexenoic acid can be made by hydrolysis of the corresponding methyl ester with base, preferably one equivalent of potassium hydroxide in an aqueous alcohol solvent. The ester of 2-oxo-5-hexenoic acid is made from methyl pyruvate as described in J. Org. Chem., (1983), 48, 158. Treatment of the triazolinone with MCPBA ( -chloroperoxybenzoic acid) in an inert solvent such as dichloromethane at a temperature between about 0°C and about 100°C, preferably at room temperature, gives an epoxide of Formula 25 (Scheme 11). Intramolecular cyclization of the epoxide using a base such as potassium carbonate in an inert solvent such as acetonitrile or acetone gives the 6-membered ring product of Formula Ic. Fluorination of the alcohol of Formula Ic with DAST (diethylaminosulfur trifluoride) at a temperature between about -78°C and about 100°C in an inert solvent such as dichloromethane gives the fluorinated product of Formula Id. 19 Scheme 11 The alcohol of Formula Ic can also be prepared by hydroxybromination of the olefϊn in the starting triazolinone using N-bromosuccinimide (ΝBS) and water or N-bromoacetamide and water followed by cyclization of the resulting bromohydrin of Formula 26 using potassium carbonate in an inert solvent such as acetonitrile or acetone (Scheme 12). Scheme 12 Compounds of Formula Ic can also be converted to the chloro-, bromo-, and iodo-R 9 substituted triazolinones of Formula I wherein J = J-2 using methods known to those skilled in the art. For example, the hydroxy group in compounds of Formula Ic can be acylated by known methods to prepare the alkylcarbonyloxy and haloalkylcarbonyloxy derivatives. In addition, the hydroxy or halo group can be converted by known methods to afford the R 9 = alkoxy and haloalkoxy derivatives (March, J., Advanced Organic Chemistry, (1992), 4th Ed., John Wiley and Sons, Inc., pp 386-389). In fact all the R 9 = OH or halogen compounds in Schemes 13-17 can be functionalized as is known in the art to prepare the other R 9 substituted compounds. Compounds of Formulae Ie and If can be prepared as illustrated in Scheme 13. Oxidative cleavage of the olefin of the triazolinone using sodium periodate and a catalytic amount of osmium tetroxide in an inert solvent mixture such as tetrahydrofuran (THF) and water, or using ozone in dichloromethane followed by reductive workup using dimethyl sulfide (DMS), affords the aldehyde of Formula 27. Intramolecular cyclization of the aldehyde under basic conditions using potassium carbonate or sodium hydride gives the 5-membered ring alcohol of Formula le. Treatment of the alcohol of Formula le with DAST in an inert solvent such as dichloromethane at a temperature between about -80°C and about 60°C produces the fluoride of Formula If. The fluoride If can also be made by direct cyclization and fluorination using DAST at a temperature range between about -100°C and about 60°C. Scheme 13 Hydroboration of the olefϊn of the triazolinone with 9-borabicyclo[3.3.1]nonane (9-BBΝ) gives the alcohol of Formula 28 after oxidative workup (Scheme 14). Oxidation of alcohol 28 with oxidizing agents such as PDC (pyridinium dichromate) produces the hemiaminal of Formula Ig presumably via the aldehyde intermediate of Formula 29. The fluoro compound of Formula Hi can be made by the treatment of the hemiaminal with DAST. Scheme 14 oxidation Triazolinones of Formula 30 can be made from 2-oxo-4-pentenoic acids and the substituted phenyl hydrazines by methods known to those skilled in the art and the methods taught herein (Scheme 10). The epoxide of Formula 31 can be prepared from the olefin of Formula 30 using an oxidant such as MCPBA. Intramolecular cyclization of the epoxide with a base such as potassium carbonate affords the alcohol of Formula Ii. The fluoro compound of Formula Ij can be made from the alcohol using DAST at a temperature between about -70°C and about room temperature in an inert solvent such as dichloromethane. Scheme 15 epoxidation K 2 Cθ3 Compounds of Formula Im can be prepared from the unsubstituted compounds of Formula 32 as illustrated in Scheme 16. Treatment of the bicyclic triazolinone of Formula 32 with N-bromosuccinimide (ΝBS) under allylic bromination conditions affords the mono-bromo derivative of Formula Ik. Hydrolysis of the bromide in hot aqueous dimethyl sulfoxide (Me 2 SO) affords the alcohol of Formula II. The fluoro compound of Formula Im can be prepared by treatment of the alcohol with diethylaminosulfur trifluoride (DAST) as described above. Scheme 16 Compounds of Formula In can be prepared as illustrated in Scheme 17. Allylic oxidation of the terminal alkene of the triazolinone with t-butyl hydroperoxide and catalytic selenium (IV) oxide in an inert solvent such as dichloromethane produces the allylic alcohol of Formula 33. Protection of the secondary alcohol as the t-butyldimethylsilyl (TBS) ether is accomplished using t-butylchlorodimethylsilane and a base, preferably triethylamine and catalytic 4-(dimethylamino)pyridine. The terminal olefin is converted to the primary alcohol to afford compounds of Formula 34 using 9-BBN followed by treatment with sodium perborate. Ring cyclization is accomplished using the Martin sulfurane dehydrating agent [CgH 5 (CF 3 ) 2 O] 2 S(CgH 5 ) . Removal of the TBS group and liberation of the alcohol can be accomplished using tetrabutylammonium fluoride. The alcohol can be converted to the corresponding fluoro compound using DAST, or to other R 9 substituted compounds as described above. Scheme 17 1) TBS-Cl, base 2) 9-BBN, NaB03 In 34 For some compounds of Formulae I and II wherein J = J-2 and R 10 is other than hydrogen, the R 10 substituent is more conveniently introduced after cyclization to form the bicyclic triazolinone. This is especially the case when R 9 and R i0 are attached to the same carbon atom. Isocyanates In some instances, the appropriate aniline is first converted to the corresponding isocyanate, and then the isocyanate is condensed with the J-group derivative, or precursor thereof, to form compounds of Formulae I and H In Scheme 18, the conversion of aniline of Formula 1 to isocyanate of Formula 35 is illustrated. Subsequent condensation of the isocyanate with the aminoester of Formula 36 forms the cyclic sulfonamide of Formula lo. The preparation of some aminoester precursors to J-6 and the condensation procedure is described in U.S. 4,179,276. Scheme 18 isocyanate foπnation 35 lo Q = 0 Compounds of Formulae I and II wherein J = J-4, J-5, J-7, J-9, J-l 1, J-12, J-13, J-14 and J-17 are also prepared by first converting the aniline to the appropriate isocyanate, and then condensation with the appropriate J-group precursor. Methods for the preparation of the J-4 precursor and the condensation are described in WO 92/11244, EP 476,697, ZA 91/00466, JP 77,874, and U.S. 3,902,887. The synthesis of the J-5 precursor and the condensation with isocyanates is described in WO 92/13453 JP 363,278, EP 230,874, and JP 2.000,985. Methods for the preparation of the J-7 precursor and the condensation with isocyanates are described in EP 484,776. Methods for the preparation of the J-9 precursor and the condensation with isocyanates are described in U.S. 5,035,740. Methods for the preparation of the J-17 precursor and its condensation with isocyanates are described in EP 493,323. The synthesis of the J-14 precursor and the condensation with isocyanates is described in J. Pesticide Sci., (1993), 18, 309. In a similar vein, the imino compounds of Formulae I and π wherein J = J-12 and J-13 can be prepared from the corresponding isocyanates of the anilines. The condensation procedure and J-group precursor preparation for compounds containing J-12 and J-13 are disclosed in EP 457,151, JP 4,145,087, EP 480,871 and DE 3,927,388. One skilled in the art will recognize that when Q or Ql is S in the desired product, the appropriate isothiocyanate is used instead of the isocyanate in the synthesis. For some compounds of Formulae I and II wherein J = J-4, J-5, J-6, J-7, J-9, J-14 and J-17, the coupling can also be accomplished starting with the aniline rather than the isocyanate. For example, the synthesis of compounds of Formula Ip (compounds of Formula I wherein R i6 and Rl 7 are taken together to form a cyclopropane ring) is illustrated in Scheme 19. Scheme 19 41 42 Treatment of cyclopropane dicarboxylic acid of Formula 37 with urea and heating to 175-185°C affords the dicarboximide of Formula 38 as described by G. C. Crockett et al. in Synth. Commun. (1981), 11, AA1-A5A. The diester of the diacid of Formula 37 is prepared by the method described by L. L. McCoy in J. Am. Chem. Soc, (1958), 80, 65-68. The diacid can be obtained by saponification of the diester using well-known methods. Reduction of the dicarboximide of Formula 38 with borane in an inert solvent, such as tetrahydrofuran (THF), followed by work-up with aqueous hydrochloric acid affords the azabicyclo[3.1.0]hexane hydrochloride of Formula 39. The reduction is preferably conducted with heating, for example in THF at reflux, as described by H. C. Brown and P. Heim in J. Org. Chem., (1973), 38, 912-916. The amine hydrochloride of Formula 39 is converted via a five step sequence to the -aminoacid of Formula 43 as illustrated. Purification of the intermediates is not necessary. Neutralization of the amine hydrochloride with a base, such as concentrated aqueous potassium hydroxide, liberates the free amine. Dissolution of the amine in an inert solvent, such as diethyl ether, and treatment with a solution of N-chlorosuccinimide (ΝCS) in an inert solvent such as ether, produces the chloramine of Formula 40. The solution of the chloramine is then treated with ethanolic potassium hydroxide to effect dehydrochlorination and give the imine of Formula 41. Once again, the imine is not purified but treated directly first with aqueous sodium bisulfite, and then with solid sodium cyanide to afford the aminonitrile of Formula 42. The reaction mixture is poured into water and extracted with a water-immiscible solvent such as ether. The organic layers are dried and evaporated under reduced pressure to afford the aminonitrile. No additional purification is necessary. The aminonitrile can be converted to the aminoacid of Formula 43 by hydrolysis with aqueous barium hydroxide followed by neutralization with sulfuric acid. A mixture of epimers at the carboxylic acid centers is obtained, and the individual diastereomers can be separated by chromatography. The acid of Formula 43 is reacted with the aniline of Formula and a trialkylaluminum reagent (e.g., trimethylaluminum), in a non-coordinating solvent such as an aromatic hydrocarbon (e.g., benzene and toluene) or halogenated hydrocarbon (e.g., methylene chloride, chloroform, carbon tetrachloride, and dichlorobutane) to obtain the amide. Generally, the reaction requires 0.1 to 48 hours at a temperature of 0°C to 25°C to proceed to completion. The amides are isolated by extraction into an organic solvent, aqueous wash, and removal of the solvent under reduced pressure. Purification can be accomplished by chromatography or recrystallization. The condensation with the amine can also be performed starting with the ester of the acid of Formula 43. The tricyclic imide of Formula Ip can be prepared from the α-aminoamide by condensation with phosgene or a phosgene equivalent. Treatment of the α-aminoamide with phosgene is preferably carried out in the presence of a tertiary-amine base such as triethylamine, pyridine, or NN-diisopropylethylamine, in an inert solvent such as dichloromethane or 1-chlorobutane. The phosgene can be added as a gas or as a solution in an inert solvent such as toluene. Suitable temperatures range from about 0°C to the reflux temperature of the solvent. l.T-Carbonyldϋmidazole, diphosgene (ClC(=O)OCCl 3 ) and triphosgene (Cl 3 COC(=O)OCCl 3 ) can also be used in a similar manner. The tricyclic imide of Formula Ip can be isolated by extraction into an organic solvent, aqueous wash, and removal of the solvent under reduced pressure. Additional purification can be accomplished by chromatography or recrystallization. Aryl Iodides For the preparation of compounds of Formulae I and II wherein J = J-l 5 and J-l 6, the appropriate aniline is first converted to the aryl alkyne as illustrated in Scheme 20. The aniline of Formula 1 is converted to the aryl iodide of Formula 44 via diazotization followed by treatment with a metal iodide salt. The aryl iodide is linked by a palladium coupling reaction to give the trimethylsilyl (TMS) alkyne. Hydrolysis of the TMS group with base affords the terminal alkyne of Formula 45. In the case of J-l 6, a [3+2] cycloaddition using a sydnone as the dipole and the alkyne as the dipolarophile affords the bicyclic pyrazole compounds. Introduction of the R 23 group affords the cyclic sulfonamides of Formula Iq. For example, treatment with N-chlorosuccinimide affords the R 23 = Cl compound. These methods are described in WO 93/15074. Scheme 20 45 iq Methods for the similar preparation of compounds of Formulae I and II wherein J = J-15 are described in JP 4,059,706, WO 92/06962, and JP 3,163,063. For compounds of Formulae I and II wherein J = J-5, the coupling can also be accomplished starting with the aniline rather than the isocyanate. For example, the synthesis of compounds of Formula Ir is illustrated in Scheme 21. Treatment of a diester of Formula 46 with an aniline of Formula 1 in the presence of a trialkylaluminum reagent (e.g., trimethylaluminum) in a non-coordinating solvent such as an aromatic hydrocarbon (e.g., benzene, toluene) or a halogenated hydrocarbon (e.g., methylene chloride, chloroform, carbon tetrachloride and dichlorobutane) affords a compound of Formula Ir. Schema 21 It is recognized that some reagents and reaction conditions described above for preparing compounds of Formulae I and II may not be compatible with certain functionalities present in the intermediates. In these instances, the incorporation of protection/deprotection sequences or functional group interconversions into the synthesis will aid in obtaining the desired products. The use and choice of the protecting groups will be apparent to one skilled in chemical synthesis (see, for example, Greene, T. W.; Wuts, P. G. M. Protective Groups in Organic Synthesis, 2nd ed.; Wiley: New York, 1991). One skilled in the art will recognize that, in some cases, after the introduction of a given reagent as it is depicted in any individual scheme, it may be necessary to perform additional routine synthetic steps not described in detail to complete the synthesis of compounds of Formulae I and H One skilled in the art will also recognize that compounds of Formulae I and II and the intermediates described herein can be subjected to various electrophilic, nucleophilic, radical, organometallic, oxidation, and reduction reactions to add substituents or modify existing substituents. Without further elaboration, it is believed that one skilled in the art using the preceding description can utilize the present invention to its fullest extent.

Useful formulations include liquids such as solutions (including emulsifiable concentrates), suspensions, emulsions (including microemulsions and/or suspoemulsions) and the like which optionally can be thickened into gels. Useful formulations further include solids such as dusts, powders, granules, pellets, tablets, films, and the like which can be water-dispersible ("wettable") or water-soluble. Active ingredient can be (micro)encapsulated and further formed into a suspension or solid formulation; alternatively the entire formulation of active ingredient can be encapsulated (or "overcoated"). Encapsulation can control or delay release of the active ingredient. Sprayable formulations can be extended in suitable media and used at spray volumes from about one to several hundred liters per hectare. High-strength compositions are primarily used as intermediates for further formulation. The formulations will typically contain effective amounts of active ingredient, diluent and surfactant within the following approximate ranges which add up to 100 percent by weight.

Typical liquid diluents are described in Marsden, Solvents Guide, 2nd Ed., Interscience, New York, 1950. McCutcheon's Detergents and Emulsifiers Annual, Allured Publ. Corp., Ridgewood, New Jersey, as well as Sisely and Wood, Encyclopedia of Surface Active Agents, Chemical Publ. Co., Inc., New York, 1964, list surfactants and recommended uses. All formulations can contain minor amounts of additives to reduce foam, caking, corrosion, microbiological growth and the like, or thickeners to increase viscosity. Surfactants include, for example, polyethoxylated alcohols, polyethoxylated alkylphenols, polyethoxylated sorbitan fatty acid esters, dialkyl sulfosuccinates, alkyl sulfates, alkylbenzene sulfonates, organosilicones, N,N-dialkyltaurates, lignin sulfonates, naphthalene sulfonate formaldehyde condensates, polycarboxylates, and polyoxyethylene/polyoxypropylene block copolymers. Solid diluents include, for example, clays such as bentonite, montmorillinite, attapulgite and kaolin, starch, sugar, silica, talc, diatomaceous earth, urea, calcium carbonate, sodium carbonate and bicarbonate, and sodium sulfate. Liquid diluents include, for example, water, N,N-dimethylformamide, dimethyl sulfoxide, N-alkylpyrrolidone, ethylene glycol, polypropylene glycol, paraffins, alkylbenzenes, alkylnaphthalenes, oils of olive, castor, linseed, tung, sesame, corn, peanut, cotton-seed, soybean, rape-seed and coconut, fatty acid esters, ketones such as cyclohexanone, 2-heptanone, isophorone and 4-hydroxy-4- methyl-2-pentanone, and alcohols such as methanol, cyclohexanol, decanol and tetrahydrofurfuryl alcohol. Solutions, including emulsifiable concentrates, can be prepared by simply mixing the ingredients. Dusts and powders can be prepared by blending and, usually, grinding as in a hammer mill or fluid-energy mill. Suspensions are usually prepared by wet-milling; see, for example, U.S. 3,060,084. Granules and pellets can be prepared by spraying the active material upon preformed granular carriers or by agglomeration techniques.

These crops and weeds were grown in the greenhouse until the plants ranged in height from two to eighteen cm (one to four leaf stage), then treated postemergence with the test chemicals formulated in a non-phytotoxic solvent mixture which includes a surfactant. Pots receiving preemergence treatments were planted immediately prior to test chemical application. Pots treated in this fashion were placed in the greenhouse and maintained according to routine greenhouse procedures. Treated plants and untreated controls were maintained in the greenhouse approximately 14-21 days after application of the test compound. Visual evaluations of plant injury responses were then recorded. Plant response ratings, summarized in Table C, are reported on a 0 to 100 scale where 0 is no effect and 100 is complete control. Compounds evaluated in this test were formulated in a non-phytotoxic solvent mixture which includes a surfactant and applied to the soil surface before plant seedlings emerged (preemergence application) and to plants that were in the one-to-four leaf stage (postemergence application). A sandy loam soil was used for the preemergence test while a mixture of sandy loam soil and greenhouse potting mix in a 60:40 ratio was used for the postemergence test. Test compounds were applied within approximately one day after planting seeds for the preemergence test. Plantings of these crops and weed species were adjusted to produce plants of appropriate size for the postemergence test. All plant species were grown using normal greenhouse practices. Crop and weed species include winter barley (Hordeum vulgare cv. 'Igri 1 ), blackgrass (Alopecurus myosuroides), chickweed (Stellaria media), downy brome (Bromus tectorum), galium (Galium aparine), green foxtail (Setaria viridis), kochia (Kochia scopaήa), lambsquarters (Chenopodium album), speedwell (Veronica persica), rape (Brassica napus), ryegrass (Lolium multiflorum), sugar beet (Beta vulgaris cv.
