Abstract

Electrooxidation of certain fluoroolefins on platinum and glass-carbon in fluorosulfonic acid has been studied. The large difference in oxidation potentials of tetrafluoroethylene and the fluorosulfate anion makes it possible to carry out fluorosulfation via an ECEC mechanism. Potentiostatic preparative electrolysis at limiting-current potentials for oxidation of tetrafluoroethylene (E=1.5 V) yields a mixture of α,ω-bis-fluorosulfates which is almost quantitative with respect to current, the main component being 1,2-bis(fluoro-sulfato)tetrafluoroethane.
