Nickel-Catalyzed C–S Coupling: Synthesis of Diaryl Sulfides Starting from Phenyldithiocarbamates and Iodobenzenes

A nickel-catalyzed C-S bond-formation protocol for the synthesis of diaryl sulfides is described. In a reaction catalyzed by NiCl2, phenyldithiocarbamates react with iodobenzenes to give diaryl sulfides smoothly in good to excellent yields (66-93%). The catalyst is cheap, the reaction is easy to carry out, the substrate scope is broad, and the yields are good. Thus, this gives an alternative way to prepare diaryl sulfides.
