An efficient and highly E-selective protocol for the synthesis of vinyl sulfones is described. This simple protocol demonstrates the first synthesis of vinyl sulfonesvia a silver-catalyzed C–S bond coupling reaction. In addition, the success of the reaction was found to be critically dependent on the use of TEMPO as the additive.

A highly efficient synthesis of vinylsulfones was achieved via decarboxylative cross-coupling reaction of cinnamic acids with aromaticsulfinic acid sodium salts catalyzed by Pd(OAc)2 and dppb in the presence of Ag2CO3. The reaction was found to furnish various vinylsulfones in good yields instead of the expected desulfitative product stilbenes. Mechanistic investigation also suggested that the decarboxylation

decarboxylative sulfonylation of cinnamic acids with sodium sulfinates for the synthesis of vinyl sulfones was developed. The reaction proceeded smoothly in the presence of Merrifield resin supported Rose Bengal ammonium salt as a photocatalyst and tert-butyl hydroperoxide (70% in water) as an oxidant in aqueous DMSO solution at roomtemperature under green LED (530-535 nm) irradiation under an air atmosphere
A stereoselective synthesis of (E)-vinyl sulfones has been developed via electrochemical oxidative N–S bond cleavage of aromatic sulfonylhydrazides, followed by cross-coupling reactions with cinnamic acids to form the C–S bond. The protocol proceeded smoothly to afford (E)-vinyl sulfones in good yields with wide substrate scope under metal-free and halogen-free conditions.
