Description: TITLE HERBICIDAL PYRAZOLES BACKGROUND OF THE INVENTION This invention relates to certain pyrazoles, their agriculturally suitable salts and compositions, and methods of their use for controlling undesirable vegetation. The control of undesired vegetation is extremely important in achieving high crop efficiency. Achievement of selective control of the growth of weeds especially in such useful crops as rice, soybean, sugar beet, corn (maize), potato, wheat, barley, tomato and plantation crops, among others, is very desirable. Unchecked weed growth in such useful crops can cause significant reduction in productivity and thereby result in increased costs to the consumer. The control of undesired vegetation in noncrop areas is also important. Many products are commercially available for these purposes, but the need continues for new compounds which are more effective, less costly, less toxic, environmentally safer or have different modes of action. SUMMARY OF THE INVENTION This invention is directed to compounds of Formula I including all geometric and stereoisomers, agriculturally suitable salts thereof, agricultural compositions containing them and their use for controlling undesirable vegetation: I wherein A is -OC(=O)-, -OC(=O)O- or -OC(=O)S-, and the directionality of the A linkage is defined such that the moiety depicted on the left side of the linkage is bonded to the pyrazole ring and the moiety on the right side of the linkage is bonded to Q; Q is C C j o alkyl optionally substituted with halogen, C2-Cg alkoxyalkyl, C 2 -Cιo alkenyl or C3-C6 cycloalkyl; or Q is phenyl, benzyl, pyridyl, furanyl or thienyl, each optionally substituted with C1 -C3 alkyl, Cj-C 3 alkoxy, cyano, halogen, COOH or S(=O) 2 OH; or A together with Q is -OC(=O)NR 6 R 7 ; R 1 is C r C 3 alkyl; R 2 and R 3 are each independently H, Ci -C 3 alkyl or halogen; R 4 and R 5 are taken together to form -O(CH 2 ) 2 O-; or R 4 and R 5 are taken together with the carbon to which they are attached to form C(=O); R 6 is C j -C β alkyl, C3-C4 alkenyl or phenyl optionally substituted with 1-3 Cj-C alkyl, C j -C 3 alkoxy, halogen or cyano; R 7 is C1-C3 alkyl or C3-C4 alkenyl; or R 6 and R 7 are taken together to form -CH 2 CH 2 CH 2 CH 2 -, -CH 2 CH 2 CH 2 CH 2 CH 2 - or -CH 2 CH 2 OCH 2 CH 2 -; provided that when A is -OC(=O)- and R 4 and R 5 are taken together to form -O(CH 2 ) 2 O-, then Q is other than C r C 2 alkyl. In the above recitations, the term "alkyl", used either alone or in compound words such as "alkylthio" or "haloalkyl" includes straight-chain or branched alkyl, such as, methyl, ethyl, «-propyl, /-propyl, or the different butyl, pentyl or hexyl isomers. The term "1-2 alkyl" indicates that one or two of the available positions for that substituent may be alkyl which are independently selected. "Alkenyl" includes straight-chain or branched alkenes such as ethenyl, 1-propenyl, 2-propenyl, and the different butenyl, pentenyl and hexenyl isomers. "Alkenyl" also includes polyenes such as 1 ,2-propadienyl and 2,4-hexadienyl. "Alkynyl" includes straight-chain or branched alkynes such as ethynyl, 1-propynyl, 2-propynyl and the different butynyl, pentynyl and hexynyl isomers. "Alkynyl" can also include moieties comprised of multiple triple bonds such as 2,5-hexadiynyl. "Alkoxy" includes, for example, methoxy, ethoxy, rc-propyloxy, isopropyloxy and the different butoxy, pentoxy and hexyloxy isomers. "Cycloalkyl" includes, for example, cyclopropyl, cyclobutyl, cyclopentyl, and cyclohexyl. The term "halogen", either alone or in compound words such as "haloalkyl", includes fluorine, chlorine, bromine or iodine. Further, when used in compound words such as "haloalkyl", said alkyl may be partially or fully substituted with halogen atoms which may be the same or different. Examples of "haloalkyl" include F 3 C, C1CH 2 , CF 3 CH 2 and CF 3 CC1 2 . The terms "haloalkenyl", "haloalkynyl", "haloalkoxy", "haloalkylthio", and the like, are defined analogously to the term "haloalkyl". The total number of carbon atoms in a substituent group is indicated by the "Cj-C;" prefix where i and j are numbers from 1 to 10. For example, C1-C3 alkylsulfonyl designates methylsulfonyl through propylsulfonyl; C 2 alkoxyalkyl designates CH 3 OCH 2 ; C 3 alkoxyalkyl designates, for example, CH 3 CH(OCH 3 ), CH 3 OCH 2 CH 2 or CH 3 CH 2 OCH 2 ; and C 4 alkoxyalkyl designates the various isomers of an alkyl group substituted with an alkoxy group containing a total of four carbon atoms, examples including CH 3 CH 2 CH 2 OCH 2 and CH 3 CH 2 OCH 2 CH 2 . Examples of "alkylcarbonyl" include C(O)CH 3 , C(O)CH 2 CH 2 CH 3 and C(O)CH(CH 3 ) 2 . Examples of "alkoxycarbonyl" include CH 3 OC(=O), CH 3 CH 2 OC(=O), CH 3 CH 2 CH 2 OC(=O), (CH 3 ) 2 CHOC(=O) and the different butoxy- or pentoxycarbonyl isomers. In the above recitations, when a compound of Formula I is comprised of one or more heterocyclic rings, all substituents are attached to - these rings through any available carbon or nitrogen by replacement of a hydrogen on said carbon or nitrogen. When a compound is substituted with a substituent bearing a subscript that indicates the number of said substituents can exceed 1 , said substituents (when they exceed 1 ) are independently selected from the group of defined substituents. Further, when the subscript indicates a range, e.g. (RM, then the number of substituents may be selected from the integers between i and j inclusive. When a group contains a substituent which can be hydrogen, for example R 2 or R 3 , then, when this substituent is taken as hydrogen, it is recognized that this is equivalent to said group being unsubstituted. Compounds of this invention can exist as one or more stereoisomers. The various stereoisomers include enantiomers, diastereomers, atropisomers and geometric isomers. One skilled in the art will appreciate that one stereoisomer may be more active and/or may exhibit beneficial effects when enriched relative to the other stereoisomer(s) or when separated from the other stereoisomer(s). Additionally, the skilled artisan knows how to separate, enrich, and/or to selectively prepare said stereoisomers. Accordingly, the present invention comprises compounds selected from Formula I and agriculturally suitable salts thereof. The compounds of the invention may be present as a mixture of stereoisomers, individual stereoisomers, or as an optically active form. The salts of the compounds of the invention include acid-addition salts with inorganic or organic acids such as hydrobromic, hydrochloric, nitric, phosphoric, sulfuric, acetic, butyric, fumaric, lactic, maleic, malonic, oxalic, propionic, salicylic, tartaric, 4-toluenesulfonic or valeric acids. The salts of the compounds of the invention also include those formed with organic bases (e.g., pyridine, ammonia, or triethylamine) or inorganic bases (e.g., hydrides, hydroxides, or carbonates of sodium, potassium, lithium, calcium, magnesium or barium) when the compound contains an acidic group such as a carboxylic acid or phenol.

DETAILS OF THE INVENTION The compounds of Formula I can be prepared by one or more of the following methods and variations as described in Scheme 1. The definitions of Q and R!-R 7 in the compounds of Formulae 1-5 below are as defined above in the Summary of the Invention. Scheme 1 illustrates the preparation of compounds of Formula I whereby a compound of Formula 1 is reacted with the appropriate reagent of Formula 2, 3, A, and 5 in the presence of a suitable base. This coupling method is carried out by general methods known in the art; see, for example, Nakamura, et al., WO 95/04054. Scheme 1 Compounds of Formula 1 can be prepared by methods described in the art; see, for example, Tseng, WO 97/01550. Compounds of Formulae 2, 3, 4, and 5 are either commercially available or can be prepared by methods well-established in the art from commercially available starting materials. It is recognized that some reagents and reaction conditions described above for preparing compounds of Formula I 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 Formula I. One skilled in the art will also recognize that it may be necessary to perform a combination of the steps illustrated in the above schemes in an order other than that implied by the particular sequence presented to prepare the compounds of Formula I. One skilled in the art will also recognize that compounds of Formula I 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.

formulation or composition with an agriculturally suitable carrier comprising at least one of a liquid diluent, a solid diluent or a surfactant. The formulation or composition ingredients are selected to be consistent with the physical properties of the active ingredient, mode of application and environmental factors such as soil type, moisture and temperature. 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. Weight Percent Active Ingredient Diluent Surfactant Water-Dispersible and Water-soluble 5-90 0-94 1-15 Granules, Tablets and Powders. Suspensions, Emulsions, Solutions 5-50 40-95 0-15 (including Emulsifiable Concentrates) Dusts 1-25 70-99 0-5 Granules and Pellets 0.01-99 5-99.99 0-15 High Strength Compositions 90-99 0-10 0-2 Typical solid diluents are described in Watkins, et al., Handbook of Insecticide Dust Diluents and Carriers, 2nd Ed., Dorland Books, Caldwell, New Jersey. 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, NN-dialkyltaurates, lignin sulfonates, naphthalene sulfonate formaldehyde condensates, polycarboxylates, and polyoxyethylene/polyoxypropylene block copolymers. Solid diluents include, for example, clays such as bentonite, montmorillonite, 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 emulsifϊable 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. See Browning, "Agglomeration", Chemical Engineering, December 4, 1967, pp 147-48, Perry's Chemical Engineer's Handbook, 4th Ed., McGraw-Hill, New York, 1963, pages 8-57 and following, and WO 91/13546. Pellets can be prepared as described in U.S. 4,172,714. Water-dispersible and water-soluble granules can be prepared as taught in U.S. 4,144,050, U.S. 3,920,442 and DE 3,246,493. Tablets can be prepared as taught in U.S. 5,180,587, U.S. 5,232,701 and U.S. 5,208,030. Films can be prepared as taught in GB 2,095,558 and U.S. 3,299,566.

Test results indicate that the compounds of the present invention are highly active preemergent and 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 fuel storage tanks, industrial storage areas, parking lots, drive-in theaters, air fields, river banks, irrigation and other waterways, around billboards and highway and railroad structures. Some of the compounds are useful for the control of selected grass and broadleaf weeds with tolerance to important agronomic crops which include but are not limited to alfalfa, barley, cotton, wheat, rape, sugar beets, corn (maize), sorghum, soybeans, rice, oats, peanuts, vegetables, tomato, potato, perennial plantation crops including coffee, cocoa, oil palm, rubber, sugarcane, citrus, grapes, fruit trees, nut trees, banana, plantain, pineapple, hops, tea and forests such as eucalyptus and conifers (e.g., loblolly pine), and turf species (e.g., Kentucky bluegrass, St. Augustine grass, Kentucky fescue and Bermuda grass). Those skilled in the art will appreciate that not all compounds are equally effective against all weeds. Alternatively, the subject compounds are useful to modify plant growth. A herbicidally effective amount of the compounds of this invention is determined by a number of factors. These factors include: formulation selected, method of application, amount and type of vegetation present, growing conditions, etc. In general, a herbicidally effective amount of compounds of this invention is 0.001 to 20 kg/ha with a preferred range of 0.004 to 1.0 kg/ha. One skilled in the art can easily determine the herbicidally effective amount necessary for the desired level of weed control. Compounds of this invention can be used alone or in combination with other commercial herbicides, insecticides or fungicides. Compounds of this invention can also be used in combination with commercial herbicide safeners such as benoxacor, dichlormid and furilazole to increase safety to certain crops.

BIOLOGICAL EXAMPLES OF THE INVENTION Test A Seeds of broadleaf signalgrass (Brachiaria decumbens), barley (Hordeum vulgare), bamyardgrass (Echinochloa crus-galli), bedstraw (Galium aparine), blackgrass (Alopecurus myosuroides), chickweed (Stellaria media), cocklebur (Xanthium strumarium), corn (Zea mays), cotton (Gossypium hirsutum), crabgrass (Digitaria sanguinalis), downy brome (Bromus tectorum), giant foxtail (Setaria faberii), lambsquarters (Chenopodium album), morningglory (Ipomoea hederacea), rape (Brassica napus), redroot pigweed (Amaranthus retroflexus), rice (Oryza sativa), sorghum (Sorghum bicolor), soybean (Glycine max), sugar beet (Retα vulgaris), velvetleaf (Abutilon theophrastϊ), wheat (Triticum aestivum), wild buckwheat (Polygonum convolvulus), wild oat (Avena fatua) and purple nutsedge (Cyperus rotundus) tubers were planted and treated preemergence with test chemicals formulated in a non-phytotoxic solvent mixture which included a surfactant. A sprayed paddy pot was treated with some designated compounds. This paddy contained rice, bamyardgrass, smallflowered flatsedge (Cyperus difformis) and duck salad (Heteranthera limosa) as the target species and was sprayed alongside the other crop and weed species. At the same time, these crop and weed species were also treated with postemergence applications of test chemicals formulated in the same manner. Plants ranged in height from 2 to 18 cm (1- to 4-leaf stage) for postemergence treatments. Treated plants and controls were maintained in a greenhouse for twelve to sixteen days, after which all species were compared to controls and visually evaluated. Plant response ratings, summarized in Table A, are based on a scale of 0 to 10 where 0 is no effect and 10 is complete control. A dash (-) response means no test result.

At the same time, these crop and weed species were also treated with postemergence applications of test chemicals formulated in the same manner. Plants ranged in height from 2 to 18 cm (1- to 4-leaf stage) for postemergence treatments. Plant species in the flood test consisted of rice (Oryza sativa), smallflower flatsedge (Cyperus difformis), duck salad (Heteranthera limosa) and bamyardgrass (Echinochloa crus-galli) grown to the 2-leaf stage for testing. Treated plants and controls were maintained in a greenhouse for twelve to sixteen days, after which all species were compared to controls and visually evaluated. Plant response ratings, summarized in Table B, are based on a scale of 0 to 10 where 0 is no effect and 10 is complete control. A dash (-) response means no test result.

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 included a surfactant. Pots receiving preemergence treatments were planted immediatley 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.

A mixture of sandy loam soil and greenhouse potting mix in a 60:40 ratio was used for the postemergence 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 annual bluegrass (Poa annua), blackgrass 2 (Alopecurus myosuroides), black nightshade (Solanum nigra), chickweed (Stellaria media), common poppy (Papaver rhoeas), deadnettle (Lamium amplexicaule), downy brome (Bromus tectorum), field violet (Viola arvensis), galium 2 (Galium aparine), green foxtail (Setaria viridis), Italian ryegrass (Lolium multiflorum), jointed goatgrass (Aegilops cylindrica), kochia (Kochia scoparia), lambsquarters (Chenopodium album), littleseed canarygrass (Phalaris minor), rape 1 (Brassica napus), redroot pigweed (Amaranthus retroflexus), Russian thistle (Salsola kali), scentless chamomile (Matricaria inodora), spring barley (Hordeum vulgare), sugar beet (Beta vulgaris), sunflower (Helianthus annuus), ivyleaf speedwell (Veronica hederaefolia), wheat (Triticum aestivum), spring wheat (Triticum aestivum), winter wheat (Triticum aestivum), wild buckwheat (Polygonum convolvulus), wild mustard (Sinapis arvensis), stages of wild oat (Avenafatua, designated 1 or 2 based upon the leaf stage of the wild oat at the time of treatment), windgrass (Apera spica-ventϊ) and winter barley (Hordeum vulgare). Treated plants and untreated controls were maintained in a greenhouse for approximately 21 to 28 days, after which all treated plants were compared to untreated controls and visually evaluated. Plant response ratings, summarized in Table D, are based upon a 0 to 100 scale where 0 is no effect and 100 is complete control. A dash response (-) means no test result.
