Controlled Synthesis of β‐Keto Sulfones and Vinyl Sulfones under Electrochemical Oxidation

Abstract Selective sulfonylation and oxosulfonylation of alkenes with sulfinates have been developed via anodic oxidation in an undivided cell. The novel electrosynthetic method provided β‐keto sulfones and vinyl sulfones with good to excellent yields in the absence of any transition metal catalyst and oxidants. Mechanism studies show that two different pathways involved in these two transformations.
