The Chan–Lam coupling reaction starting from phenyldithiocarbamates and phenylboronic acids is reported. To avoid using the volatile, hazardous, and foul-smelling thiols, which are sometimes expensive and not sufficiently available, phenyldithiocarbamates can be employed. They are demonstrated to be good sulfuration reagents in the Chan–Lam coupling to prepare biaryl sulfides. By using this protocol, dithiocarbamate substrates with a wide range of functional groups including electron-rich and electron-deficient ones are explored to obtain the desired substituted biaryl sulfides smoothly. This method is ligand-free, has a broad substrate scope, enables good yields, and is easy to perform. It provides a facile and convenient preparation of biaryl sulfides.

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.
