A copper-catalyzed sulfonylation of disulfides was achieved using sodium sulfinates in air. The reaction formed various sulfur-sulfone bonds efficiently and afforded thiosulfonates in good yields. Selenosulfonates could also be prepared with this procedure. Furthermore, both chalcogenide groups on the dichalcogenides were available in these reactions.
Copper-catalyzed synthesis of thiosulfonates by oxidative coupling of thiols with sodium sulfinates

supporting information, p. 5691 - 5694 (2014/11/07)
The copper-catalyzed sulfonylation of thiols was performed by using sodium sulfinates under an oxygen atmosphere. The procedure afforded thiosulfonates in good yields by using a CuI-Phen?H2O (Phen = 1,10-phenanthroline) catalyst and tolerated numerous combinations of arene- and alkanethiols with sodium sulfinates. Furthermore, it was found that the coupling of diaryl disulfides with sodium arylsulfinates proceeded in air and both sulfide groups on the disulfide were available.
