Abstract HSO 2 − generated from thiourea dioxide and sodium bicarbonate in aqueous CH 3 CN at 35–45°C reacted with perfluoroalkyl iodides, polyfluoroalkyl bromide, 1,1,1‐trichloro‐2,2,2‐tri‐fluoroethane and carbon tetrachloride to give the corresponding sulfinates in good yield. Furthermore, it was shown that the reagent was able to initiate the addition of perfluoroalkyl iodide to olefins and alkynes at 30°C.
