Metal-free photoredox catalyzed formation of S–C–S and C–S bonds through coupling of diaryl sulfides/benzyl chlorides with dichloromethyl derivatives

Herein presented is a metal-free photoredox strategy for constructing S–C–S and C–S bonds using diaryl disulfides with dichloromethyl/benzyl chlorides under solvent-free/aqueous conditions yields diaryl thioacetals and aryl sulfides.
