Reactions of α, ω-diiodoperfluoroalkanes with sulfur trioxide or oleum produce highly unique compounds.1, 2-Diiodotetrafluoroethane was reacted with sulfur trioxide to give an intermediate sulfate which was easily decomposed by potassium fluoride to produce difluoroiodoacetyl fluoride. The acetyl fluoride, having two adjacent reactive sites, an ICF2- and a -COF, was expected to have a high reactivity.It was reacted with metal p owders of copper and silver. The reactions produced not only the coupled perfluorosuccinyl difluoride, but also gave perfluoro-3-oxa-4-pentenoyl fluoride, a product formed by the participation of both reactive sites. The mechanism of the reaction was also discussed.
