Electrochemical Oxidation‐induced Difunctionalization of Alkynes and Alkenes with Sulfonyl Hydrazides: Facile Access to β‐Selenovinyl Sulfones and β‐Ketosulfones

Abstract We report here in an efficient electrochemical oxidative selenosulfonylation of alkynes and oxysulfonylation of alkenes without use of metal catalysts. This method provides a practical access to a wide range of β ‐(seleno)vinyl sulfones and β ‐keto sulfones. These reactions can tolerate various functional groups and be easily scaled‐up.
