Electrosynthetic access to allyl sulfones via sulfonylation of allyl bromides.

Herein, we describe a sustainable and efficient electrochemical method for the synthesis of diverse allyl sulfones under mild conditions. This electrochemical strategy enables the direct coupling of sulfonyl hydrazines with allyl bromides under mild, metal- and additive-free conditions, offering broad substrate scope, scalability, and moderate to good yields of allyl sulfones.
