Relatively unreactive aryltrifluoroethyl bromides were reacted with 1-octene in the presence of CuCl and 2,2′-bipyridyl at high temperatures. Trifluoromethylated benzyl radical was generated, and a diastereomer mixture of radical adducts was obtained with a (60–70):(40–30) diastereomer ratio. Ph3SnH reduction of the adducts gave the corresponding hydrocarbons with an isolated trifluoromethyl group
