Perfluorovinyl–metal derivatives: a new one-pot synthesis

Abstract

The one-pot reaction of the CFC replacement 1,1,1,2-tetrafluoroethane (CF 3 CFH 2 , HFC-134a) with 2 equiv. of butyllithium in diethyl ether at -78 °C followed by the addition of main-group or transition-metal halides results in good yields of the corresponding metal–perfluorovinyl compounds of high purity.
