Fluorosulfates of hexafluoroisobutylene and its higher homologs

Hexafluoroisobutylene and its higher homologs are easily reacted with SO3 to give fluorosulfates of the formula CH2═C(R)CF2OSO2F, wherein R is a linear, branched or cyclic fluoroalkyl group comprised of 1 to 10 carbon atoms and may contain ether oxygen. These compounds react under mild conditions with many nucleophiles to give CH2═C(R)CF2X, where X is derived from the nucleophile. This reaction provides a route to many substituted hexafluoroisobutylenes, which copolymerize easily with other fluoro- and hydrocarbon monomers such as vinylidene fluoride and ethylene.
