A practical transition-metal-free procedure for the synthesis of (E)-vinylsulfones through the coupling of vinylhalides with sodium sulfinates in water is reported. The reaction is strongly influenced by the presence of acids, and the use of nBu4NBr promotes its efficiency.

A photochemical halogen-bonding-assisted synthesis of vinyl sulfonesvia radical–radical cross-coupling of vinyl bromines and sodium sulfinates is developed. This methodology offers a facile and efficient approach to various vinyl sulfones with excellent functional group tolerance under metal-, photocatalyst-, base-, and oxidant-free conditions. The reaction is also applicable for the late-stage functionalization
