Trifluoromethyl radicals, plasma generation

II. Plasma-Generated Trifluoromethyl Radicals as a Synthetic Reagent.. . 181... [Pg.177]

For completeness, it should be mentioned that the reaction of trifluoromethyl radicals to replace halogens is extremely general, and not confined solely to metal species. Plasma-generated trifluoromethyl radicals will react with halocarbons according to the reaction 21)... [Pg.189]

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). ...
