Process for producing chlorophenylhydrazine compounds

A process for producing a chlorohenylhydrazine compound is disclosed, which comprises chlorinating at least one hydrogen atom on the phenyl nucleus in a beta-imidated phenylhydrazine compound and subsequently hydrolyzing the chlorinated compound. Said chlorophenylhydrazine compound is useful as starting material for the production of herbicide, insecticide and photographic coupler is produced in high yield and low cost.

N-Phenylpyrazole derivatives

N-Phenylpyrazole derivatives of the formula: STR1 (wherein each of R5 and R6 represents a C1 -C4 alkyl or alkoxy radical, a trifluoromethyl, trifluoromethoxy, nitro, cyano or primary amino radical, or a fluorine, chlorine or bromine atom, each of R7, R8 and R9 represents a hydrogen atom, a C1 -C4 alkyl or alkoxy radical, a trifluoromethyl, trifluoromethoxy, nitro, cyano or primary amino radical or a fluorine, chlorine or bromine atom, or R5, R7, R8 and R9 each represents a hydrogen atom and R6 represents a trifluoromethoxy or trifluoromethyl radical, and R10 represents a cyano radical or substituted carbamoyl radical --CONHR11, wherein R11 represents a methyl or ethyl radical) have been found to possess useful herbicidal properties. All such N-phenylpyrazole derivatives with the exception of 5-amino-4-cyano-1-(2,4-dichlorophenyl)pyrazole and 5-amino-4-cyano-1-(4-chloro-2-methylphenyl)pyrazole are new compounds. Herbicidal compositions containing such N-phenylpyrazole derivatives are described and also processes for the preparation of the new compounds.
