  • Terminal perfluoroalkylsilane compounds
    Patent number: 5011963
    Abstract: A terminal perfluoroalkylsilane compound F(CF.sub.2).sub.m (CH.sub.2).sub.n Si(CH.sub.3).sub.p X.sub.3-p (m+n=10 to 32 carbon atoms in fluoroalkyl group) is prepared by a hydrosilylation reaction of a terminal perfluoroalkene compounds F(CF.sub.2).sub.m (CH.sub.2).sub.1+q CH.dbd.CH.sub.2 (1+q+2=n) with the hydrodiensilane HSi(CH.sub.3).sub.p X.sup.3.sub.3-p. The F(CF.sub.2).sub.m (CH.sub.2).sub.1+q CH.dbd.CH.sub.2 are synthesized by a Grignard's reaction of a Grignard's reagent X.sup.2 Mg(CH.sub.2).sub.q CH.dbd.CH.sub.2 obtained from a terminal alkenyl halogen compound X.sup.2 (CH.sub.2).sub.q CH.dbd.CH.sub.2 with a terminal fluoroalkyl halogen compound F(CF.sub.2).sub.m (CH.sub.2).sub.1 X.sup.1.The terminal perfluoroalkylsilane compound has a sufficient lubricating effect and is useful for a coating agent with long and continuous lubricity.
