Room-temperature catalytic hydrodefluorination of C(sp3)-F bonds.
Room-temperature catalytic hydrodefluorination of the strong C(sp3)-F bonds in benzotrifluorides and fluoropentane is catalyzed by Et3Si[B(C6F5)4] and uses Et3SiH as the source of H. Ar-CF3 compounds are converted to Ar-CH3 and fluropentane to pentane. The reaction is thought to proceed via abstraction of F- by Et3Si[B(C6F5)4], and the substituent effects are consistent with this hypothesis.
