A novel process is described for reacting a perfluoroalkyl iodide with an olefinic compound, which comprises carrying out a free-radical addition reaction of t he perfluoroalkyl iodide to the olefin in the presence of azoic or peroxy initiator and a water-soluble salt selected from the group consisting of sulfites, bisulfite s, metabisulfites and dithionites. The adducts are obtained in high yield and purity and are useful for the preparation of oil- and water repellent products for use on paper, textiles, metal, wood and the like, or as precursors for fluorinated surfactants.
