摘　　要：描述了一种钴催化的高化学、区域、立体选择性的芳香族烯烃的脱氢硅化反应.亚胺吡啶咪唑啉的钴络合物可以有效促进该反应,并能显著提高该反应的化学选择性.该方法利用地球丰产过渡金属、廉价易得的烯烃和硅烷来构建具有高附加值的烯基硅烷.文中同时描述了该反应可放大到克级规模制备及可能的反应机理.A highly chemo-,regio-,and stereo-selective cobalt-catalyzed dehydrogenative silylation of vinylarenes was described.The imidazoline iminopyridine cobalt complex could promote this reaction effectively and improve the chemoselectivity dramatically.This protocol used earth-abundant transition metal,readily available alkenes and hydrosilanes to construct valuable vinylsilanes.The reaction could be carried out in gramscale and the proposed mechanism was also described.
