N-杂环卡宾（NHC）由于其强的末端σ-供体性质而在配位化学和均相催化中成为非常成功的配体。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NHC能够用于构建双金属和多金属架构。这篇小综述涵盖了功能化NHC配体的发展，这些配体包含额外的供体位点，以协调两个或更多的金属原子。这可以通过NHC环的N-原子、通过连接到N-原子或碳骨架的供体基团、π键或骨架上的环状π-供体的配位、或通过骨架的直接金属化。
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.
