A copolymer between tetrafluoroethylene and an alkene with this functionality that is commonly used in PEM fuel cell membranes is called Nafion.
A copolymer between tetrafluoroethylene and an alkene with this functionality that is commonly used in PEM fuel cell membranes is called Nafion. The Huls and Hoechst light-water technologies both involve the addition of this functional group to long-chain alkanes, and the products of those processes have functional uses similar to LAS compounds. A fluorocarbon compound containing this functionality, which is resistant to both oxidation and reduction and does not generate any fluoride ions, can be used as a catalyst for Friedel-Crafts acylations. A compound containing a chloride derivative of this group can be used to convert alcohols into good leaving groups for substitution reactions. In a similar reaction to nitration, compounds containing this functional group can be formed through EAS reactions. For 10 points, name this functional group found in triflic acid and tosylic acid that can be produced by reacting aromatics with sulfur trioxide or sulfuric acid.
