Abstract
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.
Claims2
A hydrosilylation method which comprises reacting
- (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, and allyl phenol, and
- (ii) a compound having a hydrogensilyl group selected from the group consisting of hydrogentrimethoxysilane, hydrogenmethyldimethoxysilane, hydrogendimethylmethoxysilane, hydrogentriethoxysilane, hydrogenmethyldiethoxysilane, hydrogendimethylethoxysilane, 1,3,5,7-tetramethyltetrasiloxane, 1,1,3,3-tetramethyldisiloxane, and pentamethyldisiloxane,
- at a temperature of from 50 to 150° C. for from 10 to 300 minutes in the presence of an acid amide compound of the formula R2—C(═O)—NH2 wherein R2 is a hydrogen atom or a monovalent hydrocarbon group of 1 to 30 carbon atoms by using catalytic action of a complex of platinum with a oxidation number of Pt(0) or Pt(II).
