Herein we report the hydroheteroarylation of vinylarenes with benzoxazole in the presence of a free abnormal N-heterocyclic carbene and Ni(COD)2, resulting in 1,1-diarylethane products exclusively. In an attempt to understand the mechanism of this catalytic reaction, two abnormal-NHC (aNHC)-coordinated Ni(II) cyclooctenyl complexes were isolated and their solid-state structures were determined by X-ray
本文中,我们报告了在存在游离的异常N杂环卡宾和Ni(COD)2的情况下,乙烯基芳烃与苯并恶唑的加氢杂芳基化反应,仅产生1,1-二芳基乙烷产品。在试图了解此催化反应的机理,双异常NHC(一个NHC)配位的镍(II)配合物环辛烯基中分离并通过X射线晶体学研究测定它们的固态结构。这些镍(II)配合物环辛烯作为活性催化剂前体原位生成一个NHC-的Ni(0)物种,其经历氧化加成与杂芳烃形成的Ni(II)氢化物中间体。
