The compounds according to this invention are suitably prepared by a variety of processes as will be described below.
In broad aspect, the preferred overall process for preparing the compounds of Formulae I-III is best viewed in the separate process steps required to get the necessary intermediates, immediate precursors and end products of the above formulae. The products of "Process I" provide the intermediates necessary for "Processes II-XVI". The products according to Formulae I-III are prepared by either a single process "II-XVI" or any combination of "Processes II-XVI". It is expressly understood that various modifications obvious to those skilled in the art are contemplated. Specific embodiments are described in Examples 1-42 below.
In the sequence of process steps described below, the various symbols defining radical substituents, e.g., R.sub.1 -R.sub.24, X, Y, etc. have the same meanings as defined for the compounds of Formulae I-III, unless otherwise qualified or limited.
Process I
This process describes the preparation of important intermediate compounds of Formula B, or isomeric mixtures thereof, which are useful in the overall process scheme for producing compounds of Formulae I-III. ##STR11##
The process for the preparation of a compound of Formula B suitably proceeds from compounds of Formula A.

Compounds of Formula A can be prepared in any anhydrous solvent or mixture of solvents; the preferred solvents are ether, alcohols, dimethylsulfoxide, toluene, benzene, etc., by reacting a substituted acetophenone in the presence of an ester with a strong base such as an alkali alkoxide, alkali amide or alkali hydride with alkali alkoxides such as sodium methoxide being preferred. Reaction temperature is in the range of -100.degree. C. to 200.degree. C., preferably -78.degree. C. to 50.degree. C. The reaction period may be chosen from the range of a few minutes to several weeks depending on the amounts of reagents, reaction temperature, etc. After completion of the reaction, the compound of Formula A is isolated by diluting the reaction mixture with water, which may be followed by acidification of the aqueous layer or, alternatively, by diluting the reaction mixture with aqueous acid. Subsequently, the product is isolated by a method such as crystallization or solvent extraction. If necessary, the product is purified by standard methods. The cyclization of this intermediate to give compounds of Formula B can be carried out in any suitable solvent by treatment with hydrazine or substituted hydrazines with alkylhydrazines being preferred. Reaction temperature is in the range of -78.degree. C. to 200.degree. C., preferably 10.degree. C. to 120.degree. C. The reaction period may be chosen from the range of a few minutes to several weeks depending on the amounts of reagents, reaction temperature, etc. The product is isolated after completion of the reaction by filtration and/or concentration of the reaction mixture. If necessary, the product is purified by standard methods such as extraction, crystallization, column chromatography, etc.
In the case of the addition of hydrazine to compounds of Formula A, the resultant pyrazole of Formula C may be treated with an alkylating agent to obtain compounds of Formula B. In this case, products of Formula B can be obtained by treatment of the above compound with an alkylating agent such as methyl iodide, benzyl bromide, allyl bromide, dimethylsulfate, etc. The preferred solvents are toluene, dimethylsulfoxide, acetone, dimethylformamide, dioxane, etc. The reaction may be carried out with or without a base. In cases in which a base is employed, alkali metal carbonates or hydroxides such as sodium carbonate or sodium hydroxide may be used. Reaction temperature is in the range of -b 78.degree. C. to 200.degree. C., preferably 10.degree. C. to 120.degree. C. The reaction period may be chosen from the range of a few minutes to several weeks depending on the amounts of reagents, reaction temperature, etc. The product is isolated after completion of the reaction by filtration and/or concentration of the reaction mixture. If necessary, the product is purified by standard methods such as extraction, crystallization, column chromatography, etc. ##STR12##

C. to the boiling point of the solvent employed. The reaction may be carried out with or without a base. In cases in which a base is employed, sodium acetate, alkali metal carbonates such as sodium carbonate or alkali metal hydroxides such as sodium hydroxide may be used. The reaction period may be chosen from the range of a few minutes to several weeks depending on the amounts of reagents, reaction temperature, etc. After completion of the reaction the product or products are isolated by concentration of the reaction mixture and the product(s) are purified by a method such as crystallization or solvent extraction. If necessary, the product(s) are further purified by standard methods.

PRE-EMERGENCE HERBICIDE TESTS
As noted above, the compounds of this invention have been found to be surprisingly effective as herbicides.
The tests for pre-emergence herbicide activity are conducted as follows:
Topsoil is placed in an aluminum pan and compacted to a depth of 0.95 to 1.27 cm from the top of the pan. On the top of the soil is placed a predetermined number of seeds of each of several monocotyledonous and dicotyledonous annual plant species and/or vegetative propagules of various perennial plant species. A known amount of the active ingredient dissolved or suspended in an organic solvent, e.g., acetone, or water as carrier is then applied directly to the seed bed, which is then covered with a layer of untreated topsoil to level fill the pan. After treatment, the pans are moved to a greenhouse bench where they are watered from below as needed to give adequate moisture for germination and growth.
Approximately 10-14 days (usually 11 days) after seeding and treating, the pans are observed and the results (% inhibition) are recorded.
Tables 7 and 7A below summarize the results of the pre-emergence herbicidal activity tests of compounds of this invention in weeds. The herbicidal rating shown in these tables is the percent inhibition of each plant species. The plant species usually regarded as weeds which are utilized in one set of tests, the data for which are shown in the tables, are identified by letter headings above the columns in accordance with the following legend:
Yens--Yellow nutsedge
Anbg--Annual bluegrass
Sejg--Seedling johnsongrass
Dobr--Downy Brome
Bygr--Barnyardgrass
Mogl--Morningglory
Cobu--Cocklebur
Vele--Velvetleaf
Inmu--Indian Mustard
Wibw--Wild buckwheat
Where noted in the tables below, the symbol "C" represents 100% control and the symbol "N" indicates that the species was planted, but no data obtained for one reason or another. Compound Nos. 1-61 are intermediate compounds and do not appear in Tables 7 and 8 below.

POST-EMERGENCE HERBICIDE TESTS
The post-emergence herbicidal activity of some of the various compounds of this invention was demonstrated by greenhouse testing in the following manner. Topsoil is placed in aluminum pans having holes in the bottom and compacted to a depth of 0.95 to 1.27 cm from the top of the pan. A predetermined number of seeds of each of several dicotyledonous and monocotyledonous annual plant species and/or vegetative propagules for the perennial plant species are placed on the soil and pressed into the soil surface. The seeds and/or vegetative propagules are covered with soil and leveled. The pans are then placed on a bench in the greenhouse and watered from below as needed. After the plants reach the desired age (two to three weeks), each pan, is removed individually to a spraying chamber and sprayed by means of an atomizer, operating at a spray pressure of 170.3 kPa (10 psig) at the application rates noted. In the spray solution is an amount of an emulsifying agent mixture to give a spray solution or suspension which contains about 0.4% by volume of the emulsifier. The spray solution or suspension contains a sufficient amount of the candidate chemical in order to give application rates of the active ingredient corresponding to those shown in Tables 8 and 8A, while applying a total amount of solution or suspension equivalent to 1870 L/Ha (200 gallons/acre). The pans were returned to the greenhouse and watered as before and the injury to the plants as compared to the control is observed at approximately 10-14 days (usually 11 days) and in some instances observed again at 24-28 days (usually 25 days) after spraying. The post-emergent herbicidal activity shown in these tables is the percent inhibition of each plant species.

The herbicidal compositions of this invention, including concentrates which require dilution prior to application, may contain at least one active ingredient and an adjuvant in liquid or solid form. The compositions are prepared by admixing the active ingredient with an adjuvant including diluents, extenders, carriers, and conditioning agents to provide compositions in the form of finely-divided particulate solids, granules, pellets, solutions, dispersions or emulsions. Thus, it is believed that the active ingredient could be used with an adjuvant such as a finely-divided solid, a liquid of organic origin, water, a wetting agent, a dispersing agent, an emulsifying agent or any suitable combination of these.
Suitable wetting agents are believed to include alkyl benzene and alkyl naphthalene sulfonates, sulfated fatty alcohols, amines or acid amides, long chain acid esters of sodium isothionate, esters of sodium sulfosuccinate, sulfated or sulfonated fatty acid esters, petroleum sulfonates, sulfonated vegetable oils, ditertiary acetylenic glycols, polyoxyethylene derivatives of alkylphenols (particularly isooctylphenol and nonylphenol) and polyoxyethylene derivatives of the mono-higher fatty acid esters of hexitol anhydrides (e.g., sorbitan). Preferred dispersants are methyl cellulose, polyvinyl alcohol, sodium lignin sulfonates, polymeric alkyl naphthalene sulfonates, sodium naphthalene sulfonate, and polymethylene bisnaphthalene sulfonate. Wettable powders are water-dispersible compositions containing one or more active ingredients, an inert solid extender and one or more wetting and dispersing agents. The inert solid extenders are usually of mineral origin such as the natural clays, diatomaceous earth and synthetic minerals derived from silica and the like. Examples of such extenders include kaolinites, attapulgite clay and synthetic magnesium silicate. The wettable powders compositions of this invention usually contain from above 0.5 to 60 parts (preferably from 5-20 parts) of active ingredient, from about 0.25 to 25 parts (preferably 1-15 parts) of wetting agent, from about 0.25 to 25 parts (preferably 1.0-15 parts) of dispersant and from 5 to about 95 parts (preferably 5-50 parts) of inert solid extender, all parts being by weight of the total composition. Where required, from about 0.1 to 2.0 parts of the solid inert extender can be replaced by a corrosion inhibitor or anti-foaming agent or both.
Other formulations include dust concentrates comprising from 0.1 to 60% by weight of the active ingredient on a suitable extender; these dusts may be diluted for application at concentrations within the range of from about 0.1-10% by weight.
Aqueous suspensions or emulsions may be prepared by stirring a nonaqueous solution of a water-insoluble active ingredient and an emulsification agent with water until uniform and then homogenizing to give stable emulsion of very finely divided particles. The resulting concentrated aqueous suspension is characterized by its extremely small particle size, so that when diluted and sprayed, coverage is very uniform. Suitable concentrations of these formulations contain from about 0.1-60%, preferably 5-50% by weight of active ingredient, the upper limit being determined by the solubility limit of active ingredient in the solvent. Concentrates are usually solutions of active ingredient in water-immiscible or partially water-immiscible solvents together with a surface active agent. Suitable solvents for the active ingredient of this invention include dimethylformamide, dimethylsulfoxide, N-methyl-pyrrolidone, hydrocarbons, and water-immiscible ethers, esters, or ketones. However, other high strength liquid concentrates may be formulated by dissolving the active ingredient in a solvent then diluting, e.g., with kerosene, to spray concentration.
The concentrate compositions herein generally contain from about 0.1 to 95 parts (preferably 5-60 parts) active ingredient, about 0.25 to 50 parts (preferably 1-25 parts) surface active agent and where required about 5 to 94 parts solvent, all parts being be weight based on the total weight of emulsifiable oil.
Granules are physically stable particulate compositions comprising active ingredient adhering to or distributed through a basic matrix of an inert, finely-divided particulate extender. In order to aid leaching of the active ingredient from the particulate extender, a surface active agent can be present in the composition. Natural clays, pyrophyllites, illite, and vermiculite are examples of operable classes of particulate mineral extenders. The preferred extenders are the porous, absorptive, preformed particles such as preformed and screened particulate attapulgite or heat expanded, particulate vermiculite and the finely-divided clays such as kaolin clays, hydrated attapulgite or bentonitic clays. These extenders are sprayed or blended with the active ingredient to form the herbicidal granules.
The granular compositions of this invention may contain from about 0.1 to about 30 parts by weight of active ingredient per 100 parts by weight of clay and 0 to about 5 parts by weight of surface active agent per 100 parts by weight of particulate clay.
The compositions of this invention can also contain other additaments, for example, fertilizers, other herbicides, other pesticides, safeners and the like used as adjuvants or in combination with any of the above-described adjuvants. Chemicals useful in combination with the active ingredients of this invention included, for example, triazines, ureas, sulfonylureas, carbamates, acetamides, acetanilides, uracils, acetic acid or phenol derivatives, thiolcarbamates, triazoles, azolopyrimidines, benzoic acid and its derivatives, nitriles, biphenyl ethers, nitrobenzenes and the like such as:

When operating in accordance with the present invention, effective amounts of the compounds of this invention are applied to the soil containing the seeds, or vegetative propagules or may be incorporated into the soil media in any convenient fashion. The application of liquid and particulate solid compositions to the soil can be carried out by conventional methods, e.g., power duster, boom and hand sprayers and spray dusters. The compositions can also be applied from airplanes as a dust or a spray because of their effectiveness at low dosages. The exact amount of active ingredient to be employed is dependent upon various factors, including the plant species and stage of development thereof, the type and condition of soil, the amount of rainfall and the specific compounds employed. In elective preemergence application or to the soil, a dosage of from about 0.02 to about 11.2 kg/ha, preferably from about 0.1 to about 5.60 kg/ha, is usually employed. Lower or higher rates may be required in some instances. One skilled in the art can readily determine from this specification, including the above examples, the optimum rate to be applied in any particular case.
The term "soil" is employed in its broadest sense to be inclusive of all conventional "soils" as defined in Webster's New International Dictionary, Second Edition, Unabridged (1961). Thus, the term refers to any substance or medium in which vegetation may take root and grow, and includes not only earth but also compost, manure, muck, humus, loam, silt, mire, clay, sand and the like, adapted to support plant growth.
Although this invention has been described with respect to specific embodiments, the details of these embodiments are not to be construed as limitations. Various equivalents, changes and modifications may be made without departing from the spirit and scope of this invention, and it is understood that such equivalent embodiments are part of this invention.
