均相催化的成功可以在很大程度上归因于各种配体框架的发展，这些配体框架已被用于调节各种系统的行为。由于环状二氨基卡宾（NHC）的强的σ-供体性质，在该领域中已经实现了惊人的结果。尽管可以粗略地调整NHC的结构，但任何多样性都远远不能与磷基对应物相匹配，而磷基对应物是后者的巨大优势之一。已知有多种稳定的无环卡宾，但它们要么不愿与金属结合，要么产生易碎的金属络合物。在过去的五年中，已经开发了新型稳定的环状卡宾以及相关的碳基配体（其不是NHC），并且其特征在于甚至更强的σ-供体性质。它们的合成和表征以及随后的配合物的稳定性，电子性质，配位行为和催化活性进行了讨论，并与他们的NHC表兄弟进行了比较。
The success of homogeneous catalysis can be attributed largely to the development of a diverse range of ligand frameworks that have been used to tune the behavior of various systems. Spectacular results in this area have been achieved using cyclic diaminocarbenes (NHCs) as a result of their strong σ-donor properties. Although it is possible to cursorily tune the structure of NHCs, any diversity is still far from matching their phosphorus-based counterparts, which is one of the great strengths of the latter. A variety of stable acyclic carbenes are known, but they are either reluctant to bind metals or they give rise to fragile metal complexes. During the last five years, new types of stable cyclic carbenes, as well as related carbon-based ligands (which are not NHCs), and which feature even stronger σ-donor properties have been developed. Their synthesis and characterization as well as the stability, electronic properties, coordination behavior, and catalytic activity of the ensuing complexes are discussed, and comparisons with their NHC cousins are made.
