Process for preparing fluoroalkyl-containing organosilicon compounds and their use

Abstract From the Canadian patent

Disclosed is a process for preparing a fluoroalkyl-containing organosilicon compound by reacting a fluorine-containing olefin with an organosilicon compound which contains at least one H-Si group, in the presence of a Pt(O) complex catalyst and, when required, recovering the fluoroalkyl-containing organosilicon compound from the reaction mixture. By the use of the Pt(O) complex catalyst the reaction may be carried out under mild conditions with a high yield and high selectivity and with virtually no isomerization. The resulting organosilicon compound may be used as a textile auxiliary or an architectural preservative or for modifying surface properties.
