Photo-induced transition-metal and photosensitizer free cross–coupling of aryl halides with disulfides

Abstract

A simple and efficient cross-coupling of aryl halides with different alkyl disulfides under mild conditions was developed. This C–S bond formation method was carried out in the absence of transition-metal and external photosensitizer under air. Excellent yields were obtained with a broad substrate scope under mild conditions, tolerating various functional groups.
