Photocatalysis has become the forefront of international chemical research due to its green and environmentally friendly characteristics. A new protocol to construct S—S(O)2 bonds using selectfluor as oxidant and eosin Y as photocatalyst under blue light irradiation was reported. This method has advantages of mild conditions, good compatibility of functional groups, and easily preparation of various symmetric or asymmetric thiosulfonates various from the corresponding mercaptans with good conversion rates. Thus, this protocol provides a very valuable reference for developing a catalytic system with mild conditions, high atomic economy and strong universality to achieve efficient and controllable conversion of sulfur-containing organic compounds.

Key words: thiol, photocatalysis, oxidative coupling, thiosulfonate
