Abstract
Direct perfluoroalkylation reactions, especially trifluoromethylations of organic substrates, are of particular importance in modern organic chemistry as they allow rapid access to perfluoroalkylated molecules. In contrast to common metal-mediated perfluoroalkylations, recently developed silver-mediated perfluoroalkylation protocols offer the opportunity for orthogonal introduction of fluorine containing groups in organic compounds. This review gathers recent progress on silver-mediated perfluoroalkylation reactions and gives an overview over efficient syntheses, properties, and reactivity of perfluoroorganosilver(I) compounds. In addition, cooperative effects with copper-mediated processes are discussed.
