The synthesis of vinyl sulfone derivatives via the reaction of arylpropiolic acids, K2S2O5, and aryl boronic acids is reported. The CuBr2/1,10-phenanthroline catalytic system in the presence of acetic acid provides the desired vinyl sulfones in moderate to good yield. Furthermore, the methodology features excellent functional group tolerance.

Palladium acetate catalyzed Mizoroki–Heck reaction of arylboronic acids with phenyl vinylsulfones afford α,β-unsaturated sulfones in good yields.
A novel phosphoric acid -mediated synthesis of vinyl sulfones through decarboxylative coupling reactions of sodium sulfinates with phenylpropiolic acids is described. This transformation is efficient and environmentally friendly.
