    Abstract: The invention comprises compounds of the general formula: in which R and R1 are identical or different aliphatic radicals having one to four carbon atoms and which may bear alkoxy groups or dialkylamino groups, and R2 and R3 are the same or different and denote hydrogen, aliphatic, cycloaliphatic, arylaliphatic or aromatic radicals which may bear halogen or alkoxyl or dialkylamino groups. The new compounds may be made by reaction of N,N1-disubstituted formamidines of the formula R-N=CH-NHR1 with an isocyanate R2NCO or a carbamyl chloride Cl-CO-N(R2)R3 and an alkaline compound. Suitable starting materials are specified. The reaction is effected at temperatures between 0 DEG and 150 DEG C., in inert solvents. Detailed examples are given. The products are used in herbicidal compositions.ALSO:A herbicidal composition comprises a compound of the formula in which R and R1 are identical or different aliphatic radicals having one to four carbon atoms and which may bear alkoxy groups or dialkylamino groups, and R2 and R3 are the same or different and denote hydrogen, aliphatic, cycloaliphatic, arylaliphatic or aromatic radicals which may bear halogen or alkoxyl or dialkylamino groups, and a carrier therefor. The compositions may be formulated as solutions, emulsions, emulsion concentrates, pastes, wettable powders, granules, suspensions or dusts. Suitable solvents are mineral oil fractions, animal or vegetable oils, cyclic hydrocarbons, alcohols, ketones, ethers, hydrocarbons, and chlorinated hydrocarbons. Quaternary ammonium compounds, soap, aliphatic sulphuric acid monoesters, aliphatic aromatic sulphonic acids, lignin-sulphonic acid, alkoxy-acetic acids, polyethylene ethers of fatty alcohols and polyethylene oxide condensation products may be used as emulsifying and dispersing agents. Solid carriers specified are talc, diatomaceous earth, kaolin, bentonite, calcium carbonate, boric acid, calcium phosphate, wood flour, cork flour, carbon and ammonium sulphate. Other substances which may be present are fatty acids, resins, glues or alginates, phenoxycarboxylic acids, substituted carboxylic anilides, triazine derivatives, urea derivatives, e.g. N-p-chlorophenyl-N1-methyl, N1-isobutinyl urea and N-cyclooctyl, N1,N1-dimethyl urea, chlorinated fatty acid esters, anhydrobenzoylanthranilic acid, bactericides, fungicides and fertilizers. Detailed examples are given.

    Abstract: The invention comprises compounds of the formulae: (R1R2N-CH2-CH2-SO2-O-) 2R, or wherein R1 and R2 represent hydrogen or an alkyl, alkenyl, cycloalkyl, hydroxyalkyl, aralkyl, aryl or -CH2-CH2-SO2-O-R radical, or jointly with the nitrogen atom represent a heterocyclic radical, R represents a tetrahydronaphthyl radical or an aryl radical which may be optionally substituted, e.g. by alkyl, chlorine, bromine or carboalkoxy, and R3 represents an alkylene radical, and salts of such compounds, e.g. with hydrochloric, sulphuric, formic and acetic acids. The above compounds are prepared by reacting a , b -unsaturated sulphonic esters of the formula R-O-SO2-CH=CH2 with ammonia, hydrazine or an appropriate amine. Specification 910,377 is referred to.ALSO:A fungicidal composition comprises an aminoethyl sulphonic ester of the formul : - or wherein R1 and R2 represent hydrogen or an alkyl, alkenyl, cycloalkyl, hydroxyalkyl, aralkyl, aryl or -CH2-CH2-SO2-O-R radical, or jointly with the nitrogen atom represent a heterocyclic radical, R represents a tetrahydronaphthyl radical or an aryl radical which may be optionally substituted, e.g. by alkyl, chlorine, bromine or carboalkoxy, and R3 represents an alkylene radical, or a salt of such compounds, e.g. with hydrochloric, sulphuric, formic or acetic acid, together with an inert solid or liquid diluent or carrier and, if desired, a dispersing or wetting agent. They may be used in admixture with other active ingredients, e.g. acaricdies, insecticides, ovicides, herbicides, fungicides and bactericides. Specification 910,377 is referred to.

    Abstract: The invention comprises compounds of formula in which R1 represents an alkyl radical with 1 to 2 carbon atoms, R2 a hydrogen atom or an alkyl radical with 1 to 3 carbon atoms or a hydroxy-substituted alkyl radical, R3 a cyclohexyl or cyclooctyl group or a group where X represents a hydrogen or chlorine atom, a hydroxyl group, or an alkyl, alkylene or an alkoxy radical containing 1 to 2 carbon atoms, and n represents 1, 2, or 3, specifically, N-p-chlorophenyl-, N-3,4-dichlorophenyl-, N-phenyl-, N-m-toyl-, N-m-(vinylphenyl)-, N-p-toyl-N1-methyl - N1-isobutinylureas. They may be prepared by the reaction of aromatic isocyanates with butinylamines or of aromatic amines with N-alkyl-N-butinylcarbamic acid derivatives such as the chlorides, in the presence of sodium or potassium alcoholates and tertiary amines. The compounds are effective as selective herbicides and may be used for post-emergence treatment.ALSO:Herbicidal compositions comprise compounds of formula in which R1 represents an alkyl radical containing 1 to 2 carbon atoms, R2 a hydrogen atom or an alkyl radical containing 1 to 3 carbon atoms or a hydroxy-substituted alkyl radical, and R3 a cyclo-hexyl or cyclo-octyl group or the group where X represents a hydrogen or chlorine atom, a hydroxyl group, or an alkyl, alkylene or alkoxy radical containing 1 to 2 carbon atoms and n represents one of the integers 1, 2 or 3, specifically N - p - chlorophenyl - N - 3,4 - di - chlorophenyl-, N-phenyl-, N-m-tolyl-, N-m-(vinylphenyl) - N - p - tolyl - N1 - methyl - N1 - isobutinyl urea, which may be used with other weed-killers such as chloro-(methyl)-phenoxyalkyl carboxylic acid derivatives, higher chlorinated carboxylic acids, e.g. a ,a -dichloro butyric acid inorganic salts such as chlorates or borax, or phenylcarbamic acid esters. They may be used as aqueous dispersions, dissolved in organic liquids, and mixed with emulsifiers, or with dry carriers as a powder. The treatment of weeds and soil infested with weeds, with aqueous dispersions using sodium lignin sulphonate as dispersing agent shows selective herbicidal results.
