Additions of perfluoroalkyl iodides R_FI to 1-alkenes can be catalyzed by transition metals, especially by noble metals such as ruthenium or platinum.Complexes of group VI-VIII metals in low oxidation states are even more effective and may also be employed for the addition of R_FI to alkynes.Heterogeneous metal catalysts facilitate the transfer of the perfluoroalkyl group from R_FI to aromatic ring systems.Iodo-perfluoroalkanes 1 belong to the most important intermediates in organofluorine chemistry.The addition of 1 to alkenes according to is known to be a radical process which can be initiated by means of heat, UV- or γ-radiation, electrocatalysis or by organic azo or peroxo compounds.We found that this type of reactions can generally be carried out using two kinds of transition metal catalysts.
