N-Heterocyclic carbenes (NHCs) have become immensely successful ligands in coordination chemistry and homogeneous catalysis due to their strong terminal σ-donor properties. However, by targeting NHC ligands with additional functionalisation, a new area of NHC coordination chemistry has developed that has enabled NHCs to be used to build up bimetallic and multimetallic architectures. This minireview covers the development of functionalised NHC ligands that incorporate additional donor sites in order to coordinate two or more metal atoms. This can be through the N-atom of the NHC ring, through a donor group attached to the N-atom or the carbon backbone, coordination of the π-bond or an annulated π-donor on the backbone, or through direct metalation of the backbone.

双金属结构中的功能化 N-杂环卡宾配体。

N-杂环卡宾(NHC)由于其强大的末端σ供体特性,已成为配位化学和均相催化中非常成功的配体。然而,通过针对 NHC 配体进行额外的功能化,NHC 配位化学的一个新领域已经开发出来,使得 NHC 能够用于构建双金属和多金属结构。这篇小综述涵盖了功能化 NHC 配体的开发,该配体结合了额外的供体位点以协调两个或多个金属原子。这可以通过 NHC 环的 N 原子、通过连接到 N 原子或碳主链的供体基团、主链上的 π 键或环状 π 供体的配位、或通过直接金属化来实现。骨干。
