promote stoichiometric Pauson–Khand reactions of enynes and CO (g). However, catalytic turnover is precluded by the strong binding of CO to the Ni2 active site. This article describes the use of M(CO)x reagents as stoichiometric CO precursors in Ni2-catalyzed carbonylation reactions. As part of these studies, well-defined heterotrinuclear Ni2Fe, Ni2Co, and Ni2Mn carbonyl clusters are synthesized using the
双镍配合物可促进烯炔和CO的化学计量的Pauson-Khand反应(g)。但是,由于CO与Ni 2活性位点之间的牢固结合而无法进行催化转化。本文介绍了M(CO)x试剂在Ni 2催化的羰基化反应中作为化学计量的CO前体的用途。作为这些研究的一部分,使用[NDI] Ni 2平台作为模板合成了定义明确的异三核Ni 2 Fe,Ni 2 Co和Ni 2 Mn羰基簇(NDI =萘啶-二亚胺)。
