Abstract

Pentafluorosulfur (VI) bromide (SF₅Br) adds to olefins of the form CX₂=CX₂, where X= H or F, with the pentafluorosulfur group usually adding to the carbon with more hydrogens attached to it. This series of compounds was used in an attempt to prepare the corresponding sulfonic acid hydrates of the general formula SF₅CX₂CX₂SO₃H·nH₂O, in order to have these compounds tested as possible fuel cell electrolytes. The reaction scheme involved reflux of the SF₅Br adduct with an equimolar amount of sodium sulfite in 50% ethanol for two days, followed by acidification of the recovered solid material using HCl or H2SO4.
