An efficient protocol for the cobalt-catalyzed preparation of diaryl sulfides from solid organozinc pivalates and commercially available diaryl disulfides is reported. This cross-coupling proceeds at room temperature and displays a good functional group tolerance, allowing the preparation of a diversity of symmetrical or asymmetrical diaryl sulfides in 60-95% yield.

An efficient ipso-thiolation of arylboronic acid esters with thiosulfonates has been achieved under mild and odorless conditions using a copper catalyst. The use of TMEDA and cesium fluoride as the ligand and base, respectively, dramatically facilitated the desired transformation. The method exhibited a broad substrate scope, which allowed for the expeditious synthesis of diverse aryl sulfides from easily available starting materials.
