Nickel-catalyzed direct C–H bond sulfenylation of acylhydrazines

Abstract

A Ni-catalyzed direct C–H bond sulfenylation of acylhydrazines was developed. The reaction used N-(pyridinyl)hydrazine as the bidentate-directing group, which can be smoothly removed through reductive N–N cleavage. This system can bear various important functional groups, providing an efficient route for the preparation of diverse diaryl sulfides.
