γ-(β-Cyanoethyl)aminopropyltriethoxysilane was synthesized from γ-aminopropyltriethoxysilane via Micheal addition with acrylonitrile. The silicon monomer was hydrolyzed and immobilized with water and fumed silica, then reacted with potassium chloroplatinite in acetone to give the title complex. The structure of this complex was characterized by elemental analysis and XPS. It has been found that the title complex is an effective catalyst for the hydrosilylation of decene, dodecene, phenyl allyl ether, allyl glycidyl ether, etc., with triethoxysilane and can be reused several times without serious loss of activity.
