Synthesis of Polyγ(βCyanoethylmercapto)propylsiloxane Platinum Complex and Its Catalytic Property
【摘要】 γ-巯丙基三乙氧基硅烷与丙烯腈反应,得到γ-(β-氰乙硫基)丙基三乙氧基硅烷.后者经气相法二氧化硅固载,再与氯亚铂酸钾反应,合成了聚γ-(β-氰乙硫基)丙基硅氧烷铂配合物.研究了该铂配合物对不饱和烃与三乙氧基硅烷的硅氢加成反应的催化特性.
【Abstract】 γ(βCyanoethylmercapto)propyltriethoxysilane has been synthesized from γmercaptopropyltriethoxysilane via Michael addition with acrylonitrile in the presence of sodium ethoxide. The silicon monomer was hydrolyzed and immobilized by water and fumed silica, then reacted with potassium chloroplatinite in acetone to give the title complex. It has been found that the title complex is an effective catalyst for hydrosilylation of decene, dodecene, phenyl allyl ether, allyl glycidyl ether, etc. with triethoxysilane and can be reused several times without any noticeable loss of activity.
