Radical addition of 2,2,2-trifluoroethyl iodide to terminal alkenes

Article abstract of DOI:10.1055/s-1992-26124

2,2,2-Trifluoroethyl iodide adds to terminal alkenes under free radical conditions in good yields if the radical initiator is added in successive portions to the reaction mixture. Reduction of the resulting secondary iodides with sodium borohydride gives the corresponding trifluoroethyl-substituted products in overall yields of 40-60%. The reaction seems to be restricted to vinyl double bonds.
