Abstract

Hydrosilylation of terminal alkenes catalyzed by a scandium metalloligand supported Ni(0) complex were studied. The anti‐Markovnikov products were obtained in 62~89% yield, along with the alkanes and 1,1,2,2‐tetraphenyldisilane as minor products. The resting‐state complexes of hydrosilylation reactions were isolated and characterized by spectroscopic method and X‐ray diffraction studies, which represent rare‐example of Ni(0) silyl complexes supported by scandium ions via a Ni(0)→Sc(III) interaction. The catalytic cycle was proposed to be redox neutral with Ni(0) center, and was facilitated by metal‐ligand cooperation involving the Ni(0)‐Si bond.

金属寡配钪负载Ni(0)配合物催化末端烯烃硅氢化反应

研究了金属寡配钪负载Ni(0)配合物催化末端烯烃的硅氢化反应。反马尔可夫尼科夫产物收率为62% ~89%，次要产物为烷烃和1,1,2,2 -四苯基二硅烷。通过光谱方法和X射线衍射研究分离并表征了氢硅化反应的静息态配合物，这是钪离子通过Ni(0)→Sc（III）相互作用负载Ni(0)硅基配合物的罕见例子。该催化循环以Ni(0)为中心为氧化还原中性，并通过Ni(0) - Si键的金属-配体配合促进。
