Hexafluoroisobutylene and its higher homologs are easily reacted with SO
3
to give fluorosulfates of the formula CH
2
═C(R)CF
2
OSO
2
F, 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 CH
2
═C(R)CF
2
X, 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.
