A method for the synthesis of gem-difluorohomoallylic alcohols by the substitution of iodine in the iododifluoromethyl group by a vinyl fragment is described. The reaction proceeds via an intramolecular iodine atom transfer followed by β-elimination. The reaction is performed in the presence of an iridium photocatalyst, fac-Ir(ppy)3, and triphenylphosphine under irradiation with light-emitting diodes.
