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.

In the synthesis of fluorotrinitromethane by reacting tetranitromethane with an adduct of an alkali metal fluoride and a fluorinated or chlorofluorinated acetone in an aprotic dipolar solvent, chlorine or bromine is added during the reaction so as to eliminate side reactions.
