A novel silver(I)-fluoride-mediated homocoupling reaction of 尾,尾-difluorostyrene derivatives is described. The transformation is initiated via nucleophilic addition of silver(I) fluoride to 尾,尾-difluorostyrenes, which is followed by dimerization of the corresponding benzylsilver intermediates. The reaction shows good substrate scope, functional group tolerance, and represents the first report on the reactivity of (伪-trifluoromethyl)benzylsilver species.
