During the last decade, organometallic, coordination, and catalytic chemistry of the three-dimensional metals such as copper (Cu) has been greatly affected by the emergence of nitrogen heterocyclic carbene (NHC) complexes. The NHCs, and in particular the mononuclear CuI-based ones, have been proven vastly useful in several applications such as in biosynthesis, catalysis, photochemistry, etc. This review tries to thoroughly describe a series of mononuclear CuI NHC complexes and their subcategories such as heteroleptics, and bidentate and tridentate heteroatom complexes, and give some detailed insights on their development, emergence, and applications. A brief outlook is also disclosed to enable other researchers to further develop a platform for future advances and studies in the field of CuI-based NHCs.

基于氮杂环碳烯的单核铜配合物：综述。

在过去的十年中，氮杂环卡宾（NHC）络合物的出现极大地影响了三维金属（例如铜）的有机金属，配位和催化化学作用。NHC，尤其是基于单核CuI的NHC已被证明在多种应用中非常有用，例如在生物合成，催化，光化学等方面。本综述试图彻底描述一系列单核CuI NHC复合物及其子类别，例如杂化剂，二齿和三齿杂原子配合物，并对其发展，出现和应用提供了一些详细的见解。还公开了简短的展望，以使其他研究人员能够进一步开发基于CuI的NHC领域的未来发展和研究平台。
