The development of homogeneous iron catalysts has been a prolific research field in recent years. Many catalytic reactions are no longer limited to noble metals. The use of N-heterocyclic carbenes (NHCs) as ancillary ligands has made substantial impact in noble metal catalysis and also started to gain popularity in iron catalysis in recent years. This review article surveys the recent literature on Fe–NHC-catalyzed chemical reactions, including C–C bond formation, reduction, and oxidation reactions.

N-杂环卡宾铁络合物的均相催化

近年来，均相铁催化剂的开发一直是多产的研究领域。许多催化反应不再局限于贵金属。N-杂环卡宾（NHC）作为辅助配体的使用已对贵金属催化产生了重大影响，并且近年来也开始在铁催化中获得普及。这篇综述文章调查了有关Fe–NHC催化化学反应的最新文献，包括C–C键的形成，还原和氧化反应。
