Abstract
Pentafluorosulfanyl fluoroaliphatic carbonyl and sulfonyl fluorides, derivatives of the acid fluorides and the preparation and use of the acid fluorides and derivatives. The fluoroaliphatic moiety of said acid fluorides comprise at least three fully-fluorinated carbon atoms. The derivatives of the acid fluorides are useful as surface-active agents and surface-treating agents.
Claims27
Fluorochemical composition comprising one or a mixture of pentafluorosulfanyl, saturated fluoroaliphatic carbonyl or sulfonyl fluorides, wherein the fluoroaliphatic moiety in said acid fluorides comprises at least three fully-fluorinated carbon atoms.
Fluorochemical composition comprising a derivative of a pentafluorosulfanyl, saturated fluoroaliphatic carbonyl or sulfonyl fluoride, said derivative having a fluoroaliphatic moiety comprising at least three fully-fluorinated carbon atoms.
Fluorochemical composition comprising a compound of the formula F.sub.5 S--R.sub.f --Z where R.sub.f is a saturated fluoroaliphatic radical having a chain of at least three fully-fluorinated carbon atoms, one of which is bonded to the sulfur atom of the F.sub.5 S moiety depicted in said formula, and Z is an organic moiety or an oxygen-containing inorganic moiety, wherein Z is a functional group capable of undergoing electrophilic, nucleophilic, or free radical reactions.
