Herein, a copper-catalyzed C?F bond defluorosilylation reaction of tetrafluoroethylene and other polyfluoroalkenes is described. Mechanistic studies, based on a series of stoichiometric reactions with copper complexes, revealed that the key steps of this defluorosilylation reaction are 1) the 1,2-addition of a silylcopper intermediate to the polyfluoroalkene and 2) a subsequent selective β-fluorine elimination, which generates a Cu?F species. The β-fluorine elimination is facilitated by Lewis acidic F?Bpin, which is generated in situ during the defluorosilylation.

An improved procedure for the preparation of trifluorovinylsilanes was established which involved addition of butyllithium to a mixture of chlorosilanes and commercially readily available chlorotrifluoroethylene at -78 to -130 deg C, and the resulting monomer was polymerized with a catalyst such as CsF or (R2N)3S(1+)*F2SiMe3(1-) to give black metallic polymer which showed conductivity of 1E-9 to 1E-10 Ω-1cm-1.
