Abstract
Via a cooperation of NHC, Si substituents and a M center, β-Si elimination was attenuated, revealing a new way to attain a high Ni-β-SiR(3):Ni-σ-SiR(3) ratio. The scope is illustrated by a head-to-tail vinylsilane-α-olefin hydroalkenylation.
摘要
通过 NHC、Si 取代基和 M 中心的合作，β-Si 消除得到了抑制，为获得高 Ni-β-SiR(3):Ni-σ-SiR(3) 比例提供了一种新途径。该范围通过头到尾乙烯基硅烷-α-烯烃氢烯丙基化反应得到了说明。
