  • Patent number: 10323049
    Abstract: The purpose of the present invention is to obtain an organosilicon compound containing an isocyanate group by thiol-ene addition reaction from a corresponding organosilicon compound having a mercapto group and an isocyanate compound having a polymerizable group. Provided is a silane coupling agent which includes a specific linking structure in which a sulfur atom is indispensably contained in a linking chain which connects an isocyanate group to a hydrolyzable silyl group. Compared to silane coupling agents for use in existing technologies, this silane coupling agent has enhanced hydrophobicity and an increased organic-moiety proportion due to the sulfur-containing linking structure.

  • Patent number: 9163037
    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.
