Abstract

Indenyl-functionalised BEt(3)-adduct NHCs were prepared by the reaction of imidazolium pro-ligands with LiBEt(3)H. This compound was converted into the indenyl-coordinate molybdenum complex dangling the NHC·BEt(3) moiety as a substituent. The stepwise coordination of NHC afforded a chelate-type mononuclear complex as well as a bimetallic complex.

摘要

通过将咪唑啉代前配体与 LiBEt(3)H 反应，制备了苯并咪唑基功能化 BEt(3)-加合物 NHC。该化合物被转化为苯并吲哚配位钼配合物，将 NHC·BEt(3)部分作为取代基悬挂。NHC 的分步配位提供了一种螯合型单核配合物以及一种双金属配合物。
