The possibility of using fluorosulfation for synthesizing perfluorovinyl and perfluorodivinyl ethers, and also perfluorocarboxylic and perfluorodicarboxylic acids, has been studied.

Electrooxidation of certain fluoroolefins on platinum and glass-carbon in fluorosulfonic acid has been studied.The large difference in oxidation potential 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(fluorosulfato)tetrafluoroethane.
OXYDATION ANODIQUE DE IODOPERFLUOROALCANES DANS LES ACIDES PERFLUOROALCANESULFONIQUES. PREPARATION DE NOUVEAUX ESTERS SULFONIQUES TOTALEMENT FLUORES RFSO3R'F A LONGUES CHAINES

Perfluorinated sulphonic esters RFSO3R'F and fluorosulphates FSO3R'F, are easily obtained by anodic oxidation of iodoperfluoroalkanes R'FI in perfluoroalkene sulphonic acids RFSO3H (RF=CF3, C2F5, C4F9) and fluorosulphuric acid.With di-iodo compound I(CF2)4I, the mono and the diester can be selectively obtained.The alkaline hydrolysis of these esters produces perfluorinated carboxylic compounds.Polyfluorinated iodide R'FCH2CH2I are also oxidized in similar conditions.The mechanism of the electrolytic reaction is discussed.
