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.

A copper/silver-cocatalyzed protocol for oxidative sulfonylation of hydrazones is demonstrated. A wide range of β-ketosulfones and N-acylsulfonamides are directly synthesized in moderate to good yields. Our work provides a viable method for scalable preparation of β-ketosulfone derivatives that have found wide applications in the pharmaceutical industry.
