Electrochemical Oxidative Cross‐Coupling Reaction to Access Unsymmetrical Thiosulfonates and Selenosulfonates

The electrochemical oxidative cross-dehydrogenative coupling of arylsulfinic acids with thiophenols was achieved via a radical process. A wide range of arylsulfinic acids and substituted thiophenols were found to be tolerated, providing unsymmetrical thiosulfonates in good to excellent yields. This electrochemical method can also be used for the reaction of arylsulfinic acids with disulfides or diselenides to obtain thiosulfonates or selenosulfonates.
