N-Heterocyclic carbenes (NHCs) can bind as two-electron sigma-donor ligands to lanthanide and actinide metal cations. In this review we summarise how the incorporation of an anionic group (alkoxide or amido), to form heterobidentate NHC ligands, allows the synthesis of a range of f-block NHC adducts. The tethering group also allows the lability of the NHC group, and its subsequent reactivity, to be
N-杂环卡宾(NHC)可以作为双电子σ供体配体与镧系元素和act系元素金属阳离子结合。在这篇综述中,我们总结了如何通过引入阴离子基团(醇盐或酰胺基)来形成异双齿NHC配体,从而合成一系列f嵌段NHC加合物。束缚基团还允许对NHC基团的不稳定性及其随后的反应性进行研究。我们包括对已知的,结构特征明确的f元素-NHC键距的简短调查,以及对取代金属结合的NHC基团做出反应的一系列底物。
