The compounds of this invention may be prepared by following the procedures described below, or by methods analogous or similar thereto and within the skill of the art. These procedures are not intended to limit the scope of the appended Claims. ##STR20##
Following Method A, an appropriately substituted aniline (I) may be treated with thiophosgene (W=S) in chloroform in the presence of potassium carbonate and water to produce the substituted phenyl isothiocyanate, (II). Alternatively, aniline (I) may be treated with phosgene (W=O) in chloroform to produce the phenyl isocyanate, (II). The reaction of (II) with the appropriate hydrazine, e.g., methylhydrazine, in ethanol (for W=S) or toluene (W=O) produces the 4-(substituted-phenyl)-2-methyl-3-thiosemicarbazide, or -semicarbazide, (III). The treatment of (III) with the appropriate anhydride, e.g., trifluoroacetic anhydride, in toluene yields the corresponding 3-substituted-4,5-dihydro-1-methyl-4-(substituted-phenyl) -1,2,4-triazol-5(1H)-thione or -one, (IV). ##STR21##
Following Method B, an appropriately substituted 4,5-dihydro-4-(nitrophenyl)-1,2,4-triazol-5(1H)-thione, (IV, R.sup.4 =--NO.sub.2) may be reduced with iron powder in dilute hydrochloric acid and ethanol to produce the corresponding 4-aminophenyl-4,5-dihydro-1,2,4-triazol-5(1H)-thione, (IV, R.sup.4 =--NH.sub.2). Subsequent reaction of (IV, R.sup.4 =--NH.sub.2) with an alkyl halide, e.g., ethyl iodide, and sodium bicarbonate in acetonitrile produces appropriately substituted 4-(mono- and dialkyl aminophenyl)-4,5-dihydro-1,2,4-triazol-5(1H)-thione, (IV, R.sup.4 =--NH(alkyl) or R.sup.4 =--N(alkyl).sub.2). ##STR22##
Following Method C, the reaction of appropriately substituted 4,5-dihydro-4-(3-methylcarbonylphenyl)-1,2,4-triazol-5(1H)-thione, (IV, R.sup.3 =--C(O)CH.sub.3), with methyltriphenylphosphonium bromide and n-butyllithium in tetrahydrofuran produces the corresponding 4,5-dihydro-4-[3-(1-methylethenyl)phenyl]-1,2,4-triazol-5(1H)-thione, (IV, R.sup.3 =--C (CH.sub.3)=CH.sub.2) . ##STR23##

The reaction of 4-(hydroxyphenyl)-4,5-dihydro-1,2,4-triazol-5(1H)-thione, (IV, R.sup.4 =--OH), with an alkyl halide, e.g., iodopropane, and potassium carbonate in N,N-dimethylformamide yields the corresponding 4,5-dihydro-4-(alkoxyphenyl)-1,2,4-triazol-5(1H)-thione, (IV, R.sup.4 =--OC.sub.3 H.sub.7). ##STR24##
Following Method E, heating a mixture of an appropriately substituted compound, (IV, W=S, R.sup.4 =F), with a cyclic amino compound such as pyrrolidine, yields the corresponding 4,5-dihydro-4-(pyrrolidin-1-yl)-phenyl-1,2,4-thiazol-5(1H)-thione, (IV, ##STR25##
Following Method F, the reaction of an appropriately substituted 4-(aminophenyl)-4,5-dihydro-1,2,4-triazol-5(1H)-thione, (IV, R.sup.4 =--NH.sub.2), prepared as described in Method B) with sodium nitrite and potassium iodide in dilute sulfuric acid produces the corresponding 4-(iodophenyl)-4,5-dihydro-1,2,4-triazol-5(1H)-thione (IV, R.sup.4 =I). Subsequent reaction of 4-(iodophenyl)-4,5-dihydro-1,2,4-triazol-5(1H)-thione, (IV, R.sup.4 =I), with copper (I) phenylacetylide in pyridine yields the substituted 4-(phenylethynylphenyl)-4,5-dihydro-1,2,4-triazol-5(1H)-thione, (IV, R.sup.4 =--C.tbd.C--C.sub.6 H.sub.5). The process described in this latter step is described in Stevens et al., J. Org. Chem., Vol. 28, pp. 3313-3315 (1963). ##STR26##
Following Method G, the reaction of a substituted 4-(iodophenyl)-4,5-dihydro-1,2,4-triazol-5(1H)-thione, (IV, R.sup.4 =I, prepared as described in Method F), with (trimethylsilyl) acetylene and a catalytic amount of bis-(triphenylphosphine) palladium (II) chloride and copper (I) iodide in a mixture of triethylamine and acetonitrile produces the substituted 4-(trimethylsilylethynylphenyl)-4,5-dihydro-1,2,4-triazol-5(1H)-thione (IV, R.sup.4 =--C.tbd.CSi(CH.sub.3).sub.3). Treatment of the resultant compound, (IV, R.sup.4 =--C.tbd.CSi(CH.sub.3).sub.3), with tetrabutylammonium fluoride in tetrahydrofuran yields the substituted 4-(ethynylphenyl)-4,5-dihydro-1,2,4-triazol-5(1H)-thione, (IV, R.sup.4 =--C.tbd.CH).
A variety of substituted aniline compounds (I) are commercially available. However, in those cases where an aniline starting material (I) having the desired substitutions is not available through commercial sources, one of the following processes may be employed. ##STR27##
Following Intermediate Method 1, a substituted aniline, for example 2,5-difluoroaniline, may be reacted with 4-methylphenylsulfonyl chloride in pyridine to form N-(4-methylphenylsulfonyl)-2,5-difluoroaniline, (V). Nitration of (V) with sodium nitrite in nitric acid, acetic acid and water produces N-(4-methylphenylsulfonyl)-2,5-difluoro-4-nitroaniline, (VI). The reaction of (VI) with aqueous sulfuric acid yields 2,5-difluoro-4-nitroaniline, (VII). Subsequent reaction of (VII) with acetic anhydride and a small amount of dimethylaminopyridine (DMAP) in methylene chloride produces N-(2,5-difluoro-4-nitrophenyl)acetamide (VIII). Treatment of (VIII) with a borane/dimethyl sulfide complex in tetrahydrofuran yields N-ethyl-2,5-difluoro-4-nitroaniline, (IX). Repeating the previous two steps, the reaction of (IX) first with acetic anhydride (to produce N-(2,5-difluoro-4-nitrophenyl)-acetamide, (X)) followed by treatment with a borane/dimethyl sulfide complex yields N,N-diethyl-2,5-difluoro-4-nitroaniline, (XI). Hydrogenation of (XI) with platinum oxide in ethanol produces the desired 2,5-difluoro-4-diethylaminoaniline, (XII). ##STR28##
Following Intermediate Method 2, the reaction of 2,5-dichloro-4-nitroaniline with acetic acid, sulfuric acid and hydrogen peroxide produces 2,6-dichloro-1,4-dinitrobenzene, (XIII). Heating the resultant compound (XIII) in diethylamine produces 2,6-dichloro-4-nitrophenyl-N,N-diethylaniline, (XIV). Subsequent hydrogenation of (XIV) with platinum oxide in ethanol provides 3,5-dichloro-4-diethylaminoaniline, (XV). ##STR29##
Following Intermediate Method 3, the reaction of catechol with 2-butanone and phosphorus pentoxide in methylene chloride produces 2-ethyl-2-methyl-1,3-benzodioxole, (XVI). Nitration of (XVI) with nitric and sulfuric acid in methylene chloride yields 2-ethyl-2-methyl-5-nitro-1,3-benzodioxole, (XVII). Subsequent hydrogenation of the compound (XVII) with platinum oxide in ethanol produces 5-amino-2-ethyl-2-methyl-1,3-benzodioxole, (XVIII). ##STR30##
Following Intermediate Method 4, the reaction of 2-hydroxy-4-nitroaniline with sodium hydride and 1,2-dibromoethane in N,N-dimethylformamide produces 2,3-dihydro-7-nitro-1,4-benzoxazine, (XIX). The reaction of (XIX) with sodium hydride and 2-iodopropane in N,N-dimethylformamide yields 2,3-dihydro-4-(1-methylethyl)-7-nitro-1,4-benzoxazine, (XX). Hydrogenation of (XX) with platinum oxide yielded (XXI). ##STR31##
Following Intermediate Method 5, the reaction of 2-chloro-5-nitropyridine, (XXII) with diethylamine produces 2-diethylamino-5-nitropyridine, (XXII). The reduction of this compound (XXII) with iron powder in aqueous hydrochloric acid and ethanol yields 5-amino-2-diethylaminopyridine, (XXIII).

The reaction mixture was neutralized with an aqueous sodium bicarbonate solution. The aqueous phase was extracted with ethyl acetate, and the organic phases were combined. The combined organic phase was dried over anhydrous magnesium sulfate and was filtered. The filtrate was evaporated under reduced pressure, leaving a residue. This residue was purified by column chromatography to yield 0.5 g of 4-(4-diethylaminophenyl)-3-trifluoromethyl-1-(2-hydroxyethyl) -4,5-dihydro-1,2,4-triazol-5(1H)-thione as an oil, Compound 171 of Table 1.

Representative compounds of the invention are set forth in Table 1. Identifying properties for these compounds are found in Table 2. The compounds are identified in Table 2 by numbers which correspond to the Compound Numbers assigned in Table 1.
The substituted-phenyl-1,2,4-triazol-5(1H)-thiones and -ones disclosed herein are useful for controlling undesired plant growth. To demonstrate this activity, representative compounds underwent pre- and postemergence evaluations using a variety of broadleaf and grasseous crops and weeds. The results of these evaluations are shown in Tables 3 and 4. The compounds are identified in Tables 3 and 4 by numbers which correspond to the Compound Numbers assigned in Table 1. The plant test species used in demonstrating the herbicidal activity of this invention included cotton (Gossypium hirsutum var. Stoneville), soybean (Glycine max var. Williams), lima bean (Phaseolus lunatus L.), field corn (Zea mays var. Agway 425x or PN3732), rice (Oryza sativa var. Labelle), wheat (Triticum aestivium var. Wheaton), field bindweed (Convolvulus arvensis), morningglory (Ipomoea lacunosa or Ipomoea hederacea) (reported as "Gloryspp" in Tables 3 and 4), velvetleaf (Abutilon theophrasti) (reported as "Velvetlf" in Tables 3 and 4), wild oat (Avena fatua ), barnyardgrass (Echinochloa crus-galli) (reported as "Barnydgr" in Tables 3 and 4), green foxtail (Setaria viridis) (reported as "Foxgreen" in Tables 3 and 4), johnsongrass (Sorghum halepense) (reported as "Johngr" in Tables 3 and 4), tomato (Lycolpersicon esculentum), and wild mustard (Brassica kaber) (reported as "Mustwild" in Tables 3 and 4).
To prepare a stock solution for testing, 0.48 gram of a compound of the invention was weighed into a flask and then dissolved in 60 ml of an aqueous acetone solution (water:acetone, 50:50) containing 0.5% (v/v) of sorbitan monolaurate emulsifier/solubilizer. Upon dissolution, the 60 ml solution was divided into two 30 ml portions, each portion being equivalent to 8.0 kg/ha when sprayed onto four 15 cm.times.25 cm test flats. One 30 ml portion was set aside for future use. The second portion was diluted with an additional 30 ml of the aqueous acetone/emulsifier solution to provide 60 ml of a-4.0 kg/ha solution. A 30 ml portion of this solution was diluted in the same manner as described above to provide 60 ml of a 2.0 kg/ha solution. Successive serial dilutions were made to provide test solutions for the remaining application rates. The test flats consisted of disposable fiber flats, 8 cm.times.15 cm.times.25 cm, which were filled to a depth of approximately 6.5 cm with steam sterilized sandy loam soil. The soil was leveled and impressed with a template to provide evenly spaced furrows 13 cm long and 0.5 cm deep in each flat. Seeds of the crops or weeds -were planted in the furrows, one species per furrow, and the template was again employed to firmly press the seeds into place. A topping soil of equal portions of sand and sandy loam soil was placed uniformly on top of each flat to a depth of approximately 0.5 cm.
For postemergence testing, the flats were planted with the test species 8 to 11 days prior to treatment. The various dilutions of the compounds of the invention were then sprayed directly onto the soil surface of the two preemergence test flats, on the foliage of the two postemergence test flats. The treated flats were maintained in a greenhouse for two weeks prior to evaluation for herbicidal activity.
Herbicidal data at application rates equivalent to 8.0 kilograms/hectare (kg/ha) and/or submultiples thereof, i.e., 4.0 kg/ha and 2.0 kg/ha, are given for various compounds of the invention in Table 3 (preemergence activity)-and Table 4 (postemergence activity). In some instances in Tables 3 and 4, the data is reported as percent kill (% K), and in other instances, the data is reported in the Tables as percent control (% C).
Percent kill, as reported in Tables 3 and 4, denotes the percentage of plants killed following application of the compounds of the invention.
Percent control, as also reported in Tables 3 and 4, is determined by a method similar to the 0 to 100 rating system disclosed in "Research Methods in Weed Science", 2nd ed., B. Truelove, ed., Southern Weed Science society, Auburn university, Auburn, Alabama, 1977. The rating system is as follows:

For use in herbicidal applications, the active compounds may be, if desired, formulated into herbicidal compositions by admixture in herbicidally effective amounts with adjuvants and carriers normally employed in the art for facilitating the dispersion of active ingredients for the particular utility desired, recognizing the fact that the formulation and mode of application of a toxicant may affect the activity of the material in a given application. Thus, for agricultural use, the present herbicidal compounds may be formulated as granules of relatively large particle size, as water-soluble or water-dispersible granules, as powdery dusts, as wettable powders, as emulsifiable concentrates, as solutions, or as any of several other known types of formulations, depending on the desired mode of application.
These herbicidal compositions may be applied either as water-diluted sprays, or dusts, or granules to the areas in which suppression of vegetation is desired. These formulations may contain as little as 0.1% to 0.2% or 0.5% to as much as 95% or more by weight of active ingredient.
Dusts are free flowing admixtures of the active ingredient with finely divided solids such as talc, natural clays, kieselguhr, flours such as walnut shell and cottonseed flours, and other organic and inorganic solids which act as dispersants and carriers for the toxicant; these finely divided solids have an average particle size of less than about 50 microns. A typical dust formulation useful herein is one containing 1.0 part or less of the herbicidal compound and 99.0 parts of talc.
Wettable powders, also useful formulations for both pre- and postemergence herbicides, are in the form of finely divided particles which disperse readily in water or other dispersant. The wettable powder is ultimately applied to the soil either as a dry dust or as an emulsion in water or other liquid. Typical carriers for wettable powders include Fuller's earth, kaolin clays, silicas, and other highly absorbent, readily wet inorganic diluents. Wettable powders normally are prepared to contain about 5-80% of active ingredient, depending on the absorbency of the carrier, and usually also contain a small amount of a wetting, dispersing or emulsifying agent to facilitate dispersion. For example, a useful wettable powder formulation contains 80.8 parts of the herbicidal compound, 17.9 parts of Palmetto clay, and 1.0 part of sodium lignosulfonate and 0.3 part of sulfonated aliphatic polyester as wetting agents. Other possible wettable powder formulations are:

Frequently, additional wetting agent and/or oil will be added to the tank-mix for postemergence application to facilitate dispersion on the foliage and absorption by the plant.
Other useful formulations for herbicidal applications are emulsifiable concentrates (ECs) which are homogeneous liquid or paste compositions dispersible in water or other dispersant, and may consist entirely of the herbicidal compound and a liquid or solid emulsifying agent, or may also contain a liquid carrier, such as xylene, heavy aromatic naphthas, isophorone, or other non-volatile organic solvent. For herbicidal application these concentrates are dispersed in water or other liquid carrier, and normally applied as a spray to the area to be treated. The percentage by weight of the essential active ingredient may vary according to the manner in which the composition is to be applied, but in general comprises 0.5 to 95% of active ingredient by weight of the herbicidal composition.
The following are examples of emulsifiable contrate formulations which may be used in herbicidal applications:

Flowable formulations are similar to ECs except that the active ingredient is suspended in a liquid carrier, generally water. Flowables, like ECs, may include a small amount of a surfactant, and contain active ingredient in the range of 0.5 to 95%, frequently from 10 to 50%, by weight of the composition. For application, flowables may be diluted in water or other liquid vehicle, and are normally applied as a spray to the area to be treated.
The following are examples of flowable formulations which may be used in herbicidal applications:

Typical wetting, dispersing or emulsifying agents used in agricultural formulations include, but are not limited to, the alkyl and alkylaryl sulfonates and sulfates and their sodium salts; alkylaryl polyether alcohols; sulfated higher alcohols; polyethylene oxides; sulfonated animal and vegetable oils; sulfonated petroleum oils; fatty acid esters of polyhydric alcohols and the ethylene oxide addition products of such esters; and the addition product of long-chain mercaptans and ethylene oxide. Many other types of useful surface-active agents are available in commerce. The surface-active agent, when used, normally comprises from 1 to 15% by weight of the composition.
Other useful formulations include simple solutions or suspensions of the active ingredient in a relatively non-volatile solvent such as water, corn oil, kerosene, propylene glycol, or other suitable solvents. The following illustrate specific suspensions which may be useful in herbicidal applications.

Other useful formulations for herbicidal applications include simple solutions of the active ingredient in a solvent in which it is completely soluble at the desired concentration, such as acetone, alkylated naphthalenes, xylene, or other organic solvents. Granular formulations, wherein the toxicant is carried on relatively coarse particles, are of particular utility for aerial distribution or for penetration of cover crop canopy. Pressurized sprays, typically aerosols wherein the active ingredient is dispersed in finely divided form as a result of vaporization of a low boiling dispersant solvent carrier, such as the Freon.TM. fluorinated hydrocarbons, may also be used. Water-soluble or water dispersible granules are also useful formulations for herbicidal application of the present compounds. Such granular formulations are free-flowing, non-dusty, and readily water-soluble or water-miscible. The soluble or dispersible granular formulations described in U.S. Pat No. 3,920,442 are useful herein with the present herbicidal compounds. In use by the farmer on the field, the granular formulations, emulsifiable concentrates, flowable concentrates, solutions, etc., may be diluted with water to give a concentration of active ingredient in the range of say 0.1% or 0.2% to 1.5% or 2%.
In addition, the active herbicidal compounds of this invention may be formulated and/or applied with insecticides, fungicides, nematicides, plant growth regulators, fertilizers, or other agricultural chemicals and may be used as effective soil sterilants as well as selective herbicides in agriculture. In applying an active compound of this invention, whether formulated alone or with other agricultural chemicals, an effective amount and concentration of the active compound is of course employed; the amount may be as low as, e.g., about 1 to about 50 g/ha, preferably about 4 to 30 g/ha. For field use, where there are losses of herbicide, higher application rates (e.g., four times the rates mentioned above) may be employed.
The active herbicidal compounds of this invention may be used in combination with other herbicides, e.g., they may be mixed with, for example, an equal or larger amount of a known herbicide such as chloroacetanilide herbicides such as 2-chloro-N-(2,6-diethylphenyl)-N-(methoxymethyl)acetamide (alachlor), 2-chloro-N-(2-ethyl-6-methylphenyl-N-(2-methoxy-1-methylethyl)acetamide (metolachlor), and N-chloroacetyl-N-(2,6-diethylphenyl)glycine (diethatyl-ethyl) benzothiadiazinone herbicides such as 3-(1-methylethyl)-(1H)-2,1, 3-benzothiadiazin-4-(3H)-one-2,2-dioxide (bentazon); triazine herbicides such as 6-chloro-N-ethyl-N-(1-methylethyl)-1,3,5-triazine-2,4-diamine (atrazine), and 2-[4-chloro-6-(ethylamino)-1,3,5-triazin-2-yl) amino-2-methylpropanenitrile (cyanazine); dinitroaniline herbicides such as 2,6-dinitro-N,N-dipropyl-4-(trifluoromethyl) benzeneamine (trifluralin); aryl urea herbicides such as N'-(3,4-dichlorophenyl)-N,N-dimethylurea (diuron) and N,N-dimethyl-N'-[3-(trifluoromethyl)phenylurea (fluo-meturon); and 2-[(2-chlorophenyl)methyl-4,4-dimethyl-3-isoxazolidinone.
As will be apparent to those skilled in the art, various modifications may be made in the formulations and application of the compounds of this invention without departing from the inventive concepts herein as defined in the claims.
