铁、钴配合物催化烯烃硅氢化反应研究进展

Research Progress in Olefin Hydrosilylation Catalyzed by Iron-and Cobalt-complexes

烯烃的硅氢化反应是有机硅化合物的重要合成反应.铂等贵金属配合物常被用于催化烯烃的硅氢化反应,但自然丰度较低、价格高昂,限制了其应用和发展.因此,开发廉价过渡金属配合物催化剂是非常有必要的.以铁、钴为代表的廉价金属配合物催化剂具有成本低、地壳含量丰富、绿色环保等优势,在烯烃的硅氢化反应中表现出较高的催化活性.综述了近年来铁、钴配合物催化烯烃硅氢化反应的研究进展,并展望了该领域存在的机遇和挑战.

The hydrosilylation of olefins is one of the important reactions for the synthesis of organosilicon com-pounds.The precious metal complexes such as platinum,are commonly used for catalyzing the hydrosilylation of ole-fins,but their low natural abundance and high price limit the application and development.Therefore,it is necessary to develop cheap transition metal complex catalysts.The cheap metal complex catalysts represented by iron and co-balt have the advantages of low cost,rich crust content,green and environmental protection,which have shown high catalytic performance in the hydrosilylation of olefins.The research progress in iron and cobalt-based catalysts to cata-lyze the hydrosilylation of olefins is reviewed,and the opportunities and challenges are also prospected.
