  摘要：

  本发明提供了一种聚硅烷支撑的过渡金属催化剂或聚硅烷/无机化合物支撑的过渡金属催化剂，其中各种类型的过渡金属由聚硅烷化合物或聚硅烷和无机化合物的组合支撑。本发明的催化剂在烃和醇中几乎不溶，在上述溶剂中用于各种有机合成反应的异相系统催化剂。支撑过渡金属的聚硅烷易于通过热处理、微波辐射、紫外线辐射或化学方法（如硅氢化反应）交联，并且在保持高催化活性的同时变得不溶于各种溶剂。此外，将聚硅烷支撑的过渡金属催化剂支撑在无机化合物上可以提高其稳定性和可操作性。这些聚硅烷支撑的过渡金属催化剂在氢化反应、硅氢化反应、Heck反应、Suzuki-Miyaura偶联反应等反应中显示出高催化活性。该催化剂易于回收和重复使用，金属泄漏极少。

  The present invention provides a polysilane-supported transition metal catalysts or a polysilane/inorganic compound-supported transition metal catalysts, wherein various types of transition metals are supported by polysilane compounds, or combination of polysilanes and inorganic compounds. The catalysts of the present invention are hardly soluble in hydrocarbons and alcohols and are useful as catalysts in heterogeneous system for various organic synthetic reactions using the above solvents. Polysilanes supporting transition metals are easily crosslinkable by thermal treatment, microwave irradiation, UV irradiation or chemical methods such as hydrosilylation reaction and are changed to be insoluble in various solvents keeping high catalytic activity. Moreover, the stability and operability of polysilane-supported transition metal catalysts will be improved by the support thereof on inorganic compounds. These polysilane-supported transition metal catalysts show a high catalytic activity in hydrogenation reaction, hydrosilylation reaction, Heck reaction, Suzuki-Miyaura coupling reactions and the like. The catalyst is easily recoverable and reusable and the leakage of metals is extremely few.
