The utility of a bipyridine periodic mesoporous organosilica, BPy-PMO, as a support material of a hydrosilylation catalyst was investigated in the hydrosilylation of phenylacetylene with trimethoxysilane. [PtMe2(BPy-PMO)] (1) exhibited a moderate catalytic activity, whereas the reaction was successfully catalysed by [PtMe2(BPy-PMO-TMS)] (2) bearing end-capped TMS groups on the surface. Spectroscopic analyses of 2 revealed that the porous structure of BPy-PMO-TMS remained almost unchanged through the reaction. The hot filtration test supported the nonleaching property of 2, thereby exhibiting good reusability without the loss of the product yields.
研究了联吡啶周期性介孔有机硅（BPy-PMO）作为硅氢加成催化剂载体材料在苯乙炔与三甲氧基硅烷硅氢加成反应中的应用。[PtMe2(BPy-PMO)]（1）表现出中等催化活性，而表面带有封端TMS基团的[PtMe2(BPy-PMO-TMS)]（2）成功催化了该反应。对2的光谱分析表明，BPy-PMO-TMS的多孔结构在反应过程中几乎保持不变。热过滤试验证实了2的非浸出性，从而显示出良好的可重复使用性，且产物收率没有损失。
