Title:
ヘキサフルオロイソブチレンおよびそのより高い同族体およびそれらの誘導体のフルオロスルファート
Document Type and Number:
Japanese Patent JP2005525428
Kind Code:
A
Abstract:
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.
