Elucidation of reactivity of new metal/silicon complexes having two types of labile bond and their application as catalysts

研究了硅与两个芳碳在金属中心具有独特的η^3配位的η^3-α-硅苯甲配合物（钼配合物1和钨配合物2）的反应活性和催化活性，得到以下结果：(1)研究了配合物1,2与有机分子（醇、酮、醛、andal烯烃）的反应，发现这些反应是通过这些配合物的金属-碳键或硅-碳键的裂解进行的。(2)我们还发现配合物1对不饱和有机分子的硅氢化具有催化活性。

Reactivity and catalytic activity of η^3-α-silabenzyl complexes (molybdenum complex1 and tungsten complex 2) bearing a unique η^3-coordination of silicon and two aromatic carbons to the metal center were studied, and we obtained the following results. (1) Reactions of complexes 1,2 with organic molecules (alcohol, ketones, aldehydes, andalkenes) were examined, and we found that the reactions proceed through cleavage of metal-carbon bonds or a silicon-carbon bond of these complexes. (2) We also revealed that complex 1 shows catalytic activity for hydrosilylation of unsaturated organic molecules.
