Synthesis of N-acyl sulfenamides via copper catalysis and their use as S-sulfenylating reagents of thiols

Abstract

Sulfenamides are organosulfur reagents that feature labile S–N bonds and have potential applications in chemical synthesis. Here, the authors report the preparation of N-acyl sulfenamides via copper-catalyzed S-amidation of thiols with dioxazolones; These N-acyl sulfenamides can be used to prepare unsymmetrical disulfides via reaction with thiols.
