An efficient synthesis of vinyl sulfones is described. Reactions of cinnamic acids with aromatic sulfinic acid sodium salts in the presence of a catalytic amount of manganese(II) acetate tetrahydrate (5 mol%) in dimethyl sulfoxide (DMSO) afforded the desired vinyl sulfones in good to excellent yields. Notably, the reaction does not need any base or iodide as additive. The use of DMSO as the solvent and running the reaction under air are critical in achieving good yields.

A highly efficient synthesis of vinylsulfones was achieved via decarboxylative cross-coupling reaction of cinnamic acids with aromatic sulfinic 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 is likely to take place after the transmetallation step. Graphical Abstract: [Figure not available: see fulltext.]
