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.
