本文介绍了在碳包覆介孔二氧化硅中构建有机钌络合物催化剂及其在硅氢加成反应多相催化剂中的应用。以2，3-二羟基萘（DN）为碳源，通过碳化反应，使[（CH 3CN）3RuCp] PF 6（Cp：CN）与C-MCM-41（[C-MCM-41-RuCp] PF 6）表面的六元碳环发生配体交换反应，合成了碳包覆介孔氧化硅（C-MCM-41）。[C-MCM-41-RuCp] PF 6的X射线吸收精细结构研究表明，所构建的钌配合物的结构与分子[（C6 H6）RuCp] PF 6的结构非常相似。[C-MCM-41-RuCp] PF 6作为一种非均相钌络合物催化剂，在固-气非均相体系中促进1-己炔与三乙基硅烷的硅氢加成反应，主要产物为α-乙烯基硅烷。
The present article describes the construction of the organoruthenium complex catalyst within carbon-coated mesoporous silica and its application to a heterogeneous catalyst for hydrosilylation reaction. The carbon-coated mesoporous silica (C-MCM-41) was synthesized by carbonization of 2,3-dihydroxynaphthalene (DN) adsorbed on the surface of mesoporous silica, followed by the ligand exchange reaction between [(CH3CN)3RuCp]PF6(Cp: cyclopentadienyl) and six-membered carbon ring at the surface of C-MCM-41 ([C-MCM-41-RuCp]PF6). X-ray absorption fine structure study for [C-MCM-41-RuCp]PF6demonstrates that the structure of the constructed ruthenium complex is closely similar to that of a molecular [(C6H6)RuCp]PF6complex. The [C-MCM-41-RuCp]PF6behaves as a heterogeneous ruthenium complex catalyst and promotes hydrosilylation of 1-hexyne by triethylsilane in a solid–gas heterogeneous system to give α-vinylsilane as a major product.
