PROCESS FOR PRODUCTION OF HYDRAZINE COMPOUND, INTERMEDIATE FOR PRODUCTION OF HYDRAZINE COMPOUND, AND PROCESS FOR PRODUCTION OF THE INTERMEDIATE

摘要

Provided are a novel method for producing a hydrazine compound useful as an insecticidal compound, and production intermediates which can be suitably used for the production method and methods for producing the intermediates. As the production intermediates, a specific isocyanate compound and an organomagnesium compound represented by the following general formula (IV) are provided. The organomagnesium compound can be synthesized from a corresponding dibromo compound.
