Trifluoromethyl radicals, plasma generation with metal atom vapors

Another procedure for the preparation of very active zinc uses the metal atom approach in which zinc-metal vapor is coprecipitated with an ethereal solvent. The unstable bis(trifluorosilyl)zinc and bis(trifluoromethyl)zinc have been prepared by cocondensing Zn atoms with -SiFs radicals see Radicals) and -CFs radicals, respectively (generated by low-temperature radio-frequency glow discharge or plasma of hexafluoroethane or hexafluorodisilane). ... 

PerfluoroaUcyl cadmium compounds are also known. Bis(trifluoromethyl)cadmium has been prepared at -78 °C by cocondensing Cd atoms with -CFs radicals generated in a hexafluoroethane plasma (see Metal Vapor Synthesis of Transition Metal Compounds),and also by the unusual reaction of activated cadmium powder with difluorodihalomethanes, for example, CF2CI2, CF2Br2, or CF2BrCl, in DMF (equation 7). ...
