An aerobic metal-free, visible-light-induced regioselective thiolation of phenols with thiophenols is reported. The cross-coupling protocol exhibits great functional group tolerance and high regioselectivity. Mechanistic studies reveal that the disulfide radical cation plays a crucial role in the visible-light catalysis of aerobic thiolation. Simply controlling the equivalent ratio of substrates enables
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 roomtemperature and displays a good functional group tolerance, allowing the preparation of a diversity of symmetrical or asymmetrical diaryl sulfides in 60–95% yield.
