Pentafluoroethanesulfonic (pentflic) acid was prepared in high yield via the corresponding lithium pentflate obtained by lithiation of pentafluoroethyl iodide, followed by sulfonylation with sulfur dioxide, oxidation by hydrogen peroxide, and hydrolysis, in a one-pot reaction without isolation of any intermediates.The prepared pentflic acid was characterized, including by its yet unreported (13)C- and (19)F-NMR spectra.

Comparative electrochemical fluorination (ECF) of ethanesulfonyl chloride and fluoride via the Simons process has been investigated. In contrast to previously reported data, the electrochemical fluorination of C2H5SO2Cl only results in low yield of C2F5SO2F and the observed product distribution pattern indicates the strong influence of the chlorination process on the decomposition of the starting material. Ethanesulfonyl fluoride serves as a suitable starting material for the high-yield syntheses of pentafluoroethanesulfonyl fluoride and pentafluoroethanesulfonic acid. The electrochemical reduction of alkane-and chloroalkane-sulfonyl chlorides was investigated by cyclic voltammetry in order to explain the behaviour of these compounds during the Simons process.

Pentafluoroethylmorpholinodifluorosulfurane was synthesized by the reaction of morpholinotrifluorosulfurane with tetrafluoroethylene in the presence of potassium fluoride and 18-crown-6.Hydrolysis of the products gave pentafluoroethanesulfinic acid, and oxidation gave pentafluoroethanesulfonic acid.The derivatives of these acids are described.
