The synthesis of vinyl sulfones via silver-promoted cross-coupling of vinyl bromides with sulfonyl hydrazides was realized. Water was used as the sole solvent. Multisubstituted vinyl sulfones were easily prepared with excellent alkyl group tolerance. A mechanism involving nucleophilic attack of a sulfinate anion was proposed.

Arenesulfonyl chlorides react with vinylarenes in the presence of dichlorotris(triphenylphosphine)ruthenium(II) catalyst and 1 molar equiv of a tertiary amine to form α,β-unsaturated sulfones 2.Only the E isomers of the sulfones are formed.In reactions of arenesulfonyl chlorides containing an electron-withdrawing Cl or NO2 substituent with α-methylstyrenes, 2-aryl-3-(arylsulfonyl)propenes (5) are also formed.Mechanisms for these reactions are proposed.
