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.

EP 283,261 discloses heterocycles of Formula i as herbicides: wherein X, X1 and X2 are independently 0 or S; R1 is a monocyclic or fused-bicyclic heterocyclic group optionally substituted by one or more groups selected from oxo, mercapto, halo, nitro, cyano, amino, mono- or dialkylamino, amido, alkyl, alkenyl, alkynyl, cycloalkyl, haloalkyl, haloalkoxy, aryl, hydroxy, alkoxy, alkoxycarbonyl, alkylcarbonyl, mono- or dialkylcarbamoyl, alkylthio, alkylsulfinyl, alkylsulfonyl, sufonamido, alkylcarbonyloxy, alkylcarbonylamino or heterocyclyl; and Y is, inter alia, C2-C4 alkylene.

The salts of the present invention are not disclosed in this reference.

SUMMARY OF THE INVENTION This invention is directed to compounds of Formula I including all geometric and stereo isomers, agricultural compositions containing them and their use for controlling undesirable vegetation:

wherein Qis M is Li, Na, K, Ca, Mg, Co, Ni, Cu or Zn; or M is r is 1 when M is Li, Na, K or r is 2 when M is Ca, Mg, Co, Ni, Cu or Zn; R1 and R2 are taken together with the carbon to which they are attached to form C(=O) or R1 and R2 are taken together to form -OCH2CH2O- optionally substituted with one to two Cl-C3 alkyl; each R3 is CH3; R4 and R5 are each independently H, C1 -C3 alkyl or halogen; R6 is Cl-C3 alkyl; R7 is C1-C3 alkyl; R8 is H, C1-C25 alkyl or benzyl; R9 and R10 are independently C1-C25 alkyl;

R1 l is C1-C25 alkyl or R12 is H, Cl-Cz, alkyl, Cl-C3 alkoxy, NO9 or CN; m and t are independently 1, 2 or 3; n and p are each independently 0, 1 or 2; and qisO, 1,2, 3 or 4; provided that when Q is Q-1 and R1 and R2 are taken together with the carbon to which they are attached to form C(=O), then n is 1 or 2.

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, n-propyl, i-propyl, or the different butyl, pentyl or hexyl isomers. "Alkoxy" includes, for example, methoxy, ethoxy, n-propyloxy, isopropyloxy and the different butoxy, pentoxy and hexyloxy isomers.

The term "halogen", either alone or in compound words such as "haloalkyl", includes fluorine, chlorine, bromine or iodine.

The total number of carbon atoms in a substituent group is indicated by the "Cj-Cj" prefix where i andj are numbers from 1 to 25. For example, C1-C3 alkyl designates methyl through propyl.

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.

When a group contains a substituent which can be hydrogen, for example R12, 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.

Some compounds of this invention can exist as one or more tautomers. One skilled in the art will recognize, for example, that compounds of Formula Ia (Formula I where Q is

Q-1) can also exist as other tautomers as shown below. One skilled in the art will recognize that said tautomers often exist in equilibrium with each other. As these tautomers interconvert under environmental and physiological conditions, they provide the same useful biological effects. The present invention includes mixtures of such tautomers as well as the individual tautomers of compounds of Formula I. + R1 R2 (R3)< < ; (R6)q (°)n RS 7 Ia ¼ wherein M is Na Rl R2 R4 Na+ R1 R2 R4 o Na O (R3,,- A AS >< AS R3 R3 Preferred compounds for reasons of better activity and/or ease of synthesis are: Preferred 1.

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 Schemes 1-13. The definitions ofQ, R1-R12, M, m, n, p, q, and r in the compounds of Formulae 1-1 1 below are as defined above in the Summary of the

Invention. Compounds of Formulae Ia and Ib are subsets of the compounds of Formula I, and all substituents for Formulae Ia and Ib are as defined above for Formula I. For example, compounds of Formula Ia below are compounds of Formula I wherein Q is Q-1.

Scheme 1 illustrates the preparation of compounds of Formula Ia whereby an enol of Formula 1 is treated with an alkali metal alkoxide in an alcoholic solvent such as methanol or ethanol. When M is Ca or Mg, compounds of Formula Ia may be prepared by the treatment of an enol of Formula 1 with a calcium or magnesium alkoxide. When M is a quaternary ammonium salt, compounds of Formula Ia may be prepared by the treatment of an enol of Formula 1 with a suitable quaternary ammonium halide salt and a base. This conversion is carried out by methods are known in the art (or by slight modification of these methods).

This conversion is carried out by methods known in the art (or by slight modification of these methods): for example; see P. A. Grieco, et al., J: Am. Chem.

Alternatively, the triethylammonium salt of 1 a can be isolated directly; this method is preferred for compounds which may be sensitive to the acidic workup conditions. Treatment of the triethylammonium salt of 1 a with aqueous alkali metal hydroxides yields the corresponding alkali metal salt of Formula Ia.

The reaction may be buffered with a base such as sodium acetate or sodium carbonate. The oxidation is carried out by general methods known in the art (see for example, B. M. Trost, et al., J. Org. Chem. (1988), 53, 532; B. M. Trost, et al., Tetrahedron Lett. (1981), 21, 1287; S. Patai, et al., The Chemistry ofSulphones and Suiphoxides, John Wiley & Sons).

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 suspenslon 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.

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 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. 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.

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.

A sandy loam soil was used for the preemergence and postemergence tests, while a silt loam soil was used in the flood test. Water depth was approximately 2.5 cm for the flood test and was maintained at this level for the duration of the test.

Plant species in the preemergence and postemergence tests consisted of barnyardgrass (Echinochloa crus-galli), barley (Hordeum vulgare), bedstraw (Galium aparine), black grass (A lopecurus myosuroides), chickweed (Stellaria media), cocklebur (Xanthium strumarium), corn (Zea mays cv. Pioneer 3394), cotton (Gossypium hirsutum), crab grass (Digitaria sanguinalis), downy brome (Bromus tectorum), giant foxtail (Setariafaberii), johnsongrass (Sorghum halpense), lambsquarters (Chenopodium album), morningglory (Ipomoea hederacea), pigweed (Amaranthus retroflexus), rape (Brassica napus), rye grass (Lolium multiflorum), soybean (Glycine max), speedwell (Veronicapersica), sugar beet (Beta vulgaris), velvetleaf (Abutilon theophrasti), wheat (Triticum aestivum), wild buckwheat (Polygonum convolvulus), and wild oat (Avenafatua).

Plant species in the flood test consisted of rice (Oryza sativa), umbrella sedge (Cyperus difformis), duck salad (Heteranthera limosa), barnyardgrass (Echinochloa crus-galli, designated as 'barnyardgrassl') and late watergrass (Echinochloa oryzicola) grown to the 2- leaf stage for testing.

All plant species were planted one day before application of the formulated compound for the preemergence portion of this test. Plantings of these species were adjusted to produce plants of appropriate size for the postemergence portion of the test. All plant species were grown using normal greenhouse practices.

TEST F Plastic pots were partially filled with silt loam soil. The soil was then saturated with water. Indica Rice (Oryza sativa) seed (designated rice, indica 1) and seedlings (designated rice, indica 3) at the 2 leaf stage, seeds, tubers or plant parts selected from barnyardgrass (Echinochloa crus-galli), ducksalad (Heteranthera limosa), early watergrass (Echinochloa oryzoides), junglerice (Echinochloa colonum), late watergrass (Echinochloa oryzicola), red stem (Ammania species), rice flatsedge (Cyperus iria), small flower flatsedge (Cyperus difformis) and tighthead sprangletop (Leptochloafasicularis), were planted into this soil.

Plantings and waterings of these crops and weed species were adjusted to produce plants of appropriate size for the test. At the 2-leaf stage, water levels were raised to 3 cm above the soil surface and maintained at this level throughout the test. Chemical treatments were formulated in a non-phytotoxic solvent mixture which included a surfactant and applied directly to the paddy water by pipette, or to the plant foliage by an air pressure-assisted, calibrated belt-conveyer spray system.

Treated plants and controls were maintained in a greenhouse for approximately 21 days, after which all species were compared to controls and visually evaluated. Plant response ratings, summarized in Table F, are reported on a 0 to 100 scale where 0 is no effect and 100 is complete control. A dash (-) response means no test result.
