A hydrosilylation method is provided. In this hydrosilylation method, silylation of the carbon atom other than the terminal carbon atom and generation of the by-product isomer by internal migration of the double bond are suppressed without sacrificing the hydrosilylation reactivity, even if an olefin compound having tertiary amine atom which can be a catalyst poison was used. In the hydrosilylation, an olefin compound having carbon-carbon unsaturated bond, and a compound having hydrogensilyl group are reacted in the presence of an acid amide compound, a nitrile compound and an aromatic hydroxyl compound, or an organoamine salt compound, by using catalytic action of platinum and/or its complex compound. |

1. A hydrosilylation method wherein
(i) an olefin compound having a carbon-carbon unsaturated bond selected from the group consisting of: an olefin compound selected from the group consisting of allyl isocyanate, triallyl isocyanurate, 1,3-butadiene, isoprene, 1,4-pentadiene, 1,5-hexadiene, 1,6-heptadiene, 1,7-octadiene, 1,8-nonadiene, 1,9-decadiene, divinylcyclohexane, trivinylcyclohexane, diallylcyclohexane, triallylcyclohexane, styrene, allyl benzene, and allyl phenol; a diene compound of formula (4):
CH2═C(R4)—(CH2)m—C(R4)═CH2 (4)wherein R4 is independently hydrogen atom or a monovalent hydrocarbon group and m is an integer of 0 to 20; and a compound containing an aliphatic ring structure and/or an aromatic ring structure having vinyl group or allyl group, and
(ii) a compound having a hydrogensilyl group selected from the group consisting of hydrogentrimethoxysilane, hydrogenmethyldimethoxysilane, hydrogendimethylmethoxysilane, hydrogentriethoxysilane, hydrogenmethyldiethoxysilane, hydrogendimethylethoxysilane, hydrogentri(2-propenoxy)silane, hydrogenmethyldi(2-propenoxy)silane, hydrogendimethyl(2-propenoxy)silane, organopolysiloxane and organosilsesquioxane having a hydrosilyl group produced by hydrolytic condensation of one of said silane monomers, 1,3,5,7-tetramethyltetrasiloxane, 1,1,3,3-tetramethyldisiloxane, pentamethyldisiloxane, and dimethyl silicone polymer containing 3 to 100 silicon atoms having a hydrosilyl group on its side chain or at its terminalare reacted in the presence of a nitrile compound selected from the group consisting of acetonitrile, acrylonitrile, propane nitrile, butane nitrile, and benzonitrile and an aromatic hydroxyl compound selected from the group consisting of phenol, hydroquinone, cresol, and bisphenol A1 at a molar ratio of nitrile compound to aromatic hydroxyl compound in the range 1:1 to 100:1 by using catalytic action of platinum and/or its complex compound to form a hydrosilylated derivative of said olefin compound. |
