    Abstract: The invention comprises a compound of formula PhNHCON(Me)OCHMeC­CH in which the phenyl group may be substituted by up to 2 Cl or alkyl radicals. Standard etherification and urea-formation reactions are used. Specified substituents are 3- or 4-Cl; 2-, 3- or 4-Me or Et; 3,4-Cl2; 3-Cl-4-Me, and 3-Me-4-Cl.ALSO:Herbicides contain compounds of formula PhNHCON(Me)OCHMeC­CH in which the phenyl group may be substituted by up to 2 Cl or alkyl radicals. These compounds are stated to be oil-soluble and readily emulsifiable, and may be used together with other herbicides such as ureas, s-triazines, pyridazones, carbamates, thiocarbamates, uracils and borates.

    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.
