title: Gold-catalyzed intermolecular C-S bond formation: efficient synthesis of α-substituted vinyl sulfones.
abstract: A general method for the synthesis of α-substituted vinyl sulfones makes use of a combination of a triazole gold complex and gallium triflate. This efficient CS bond formation between simple terminal alkynes and sulfinic acids provides access to various α-substituted vinyl sulfones.
