A facile and eco‐friendly visible light‐mediated synthesis of symmetrical and unsymmetrical disulfides using tris[2‐phenylpyridinato‐C2,N]iridium(III) under additive and oxidant free conditions has been disclosed. The developed method is very mild, several functional group tolerant and highly atom economical requiring extremely low amount of catalyst loading (0.5 mol%).

A facile and rapid synthesis of unsymmetrical aryl disulfides using PPh3-mediated reductive coupling of thiophenols with arylsulfonylchlorides was described. Good functional group tolerance and scalability were achieved in this strategy. More importantly, the approach enables the introduction of sulfonylchlorides into the synthesis of asymmetric organic disulfides under catalyst- and base-free conditions
