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.

Preparation of 2,4,6-trichlorophenylhydrazine

Disclosed is a process for the preparation of 2,4,6-trichlorophenylhydrazine by chlorinating the reaction product of phenylhydrazine and a dicarboxylic anhydride to obtain an N-(2,4,6-trichloroanilino)dicarboximide which is reacted with a base capable of liberating 2,4,6-trichlorophenylhydrazine therefrom.
