method for the synthesis of unsymmetrical disulfides is reported. Using sodium sulfites and 2-mercaptobenzo heterocyclic compounds as starting materials, the unsymmetrical sulfur–sulfur bonds could be quickly constructed in the PPh3/I2 reaction system under transition–metal-free conditions. This protocol has the advantages of mild reaction conditions, easily available starting materials, and wide substrate
