Document Type and Number:
Japanese Patent JP2921672
Kind Code:
B2
Abstract:
Preparation of organosilanes of formula (I) and/or (IA) is claimed by reaction of a chlorosilane (II) with a methylhydrogensilane (III) in the presence of a phosphonium catalyst (IV). In the formulae: R = alkyl, aryl, alkaryl or haloalkyl; X = halogen; a, b, y and z = 1 or 2; and c = 2 or 3. Also claimed is a novel catalyst (IV) and its preparation by reacting a phosphonium compound of formula R<1>mP<+>R<2>4-m-SiYpR<3>3-pX<-> (V) in a solvent with a carrier. In the formulae: R<1> = 1-20C monovalent hydrocarbon or 2 R together form a 4-11C divalent hydrocarbon opt. interrupted by a heteroatom; R<2> = mono- or di-valent 1-20C hydrocarbon; m = 1, 2 or 3 (=3 in compound (V) used in the catalyst preparation); n = 0 or 1, with m = 3 when n = 1; T = an oxygen-bonded carrier; R<3> = 1-12C monovalent hydrocarbon; p = 1, 2 or 3; and Y = a hydrolysable group. ZRaSiCl4-a (II) + CH3SiHcX3-c (III) -> ZRaSiHbCl4-a-b (I) + CH3SiHc-yX3+y-c (IA) The reaction proceeds under the action of a catalyst given by (IV). (R<1>mP<+>R<2>4-m)ÄSi(OT)pR<3>3-pÜX<-> (IV)
