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 13C- and 19F-NMR spectra.
