N-杂环卡宾（NHC）和环状（烷基）（氨基）卡宾（CAAC）引起了人们的极大兴趣，因为它们的电子和空间特性提供了一类独特的配体和有机催化剂。在此，研究了涉及铑和镍的新型羰基配合物的取代反应，以更深入地了解表征 CAAC(methyl) 的基本电子因素，并将其与 NHC 和空间要求更高的 CAAC 配体的大量可用数据进行比较。
N-heterocyclic carbenes (NHCs) and cyclic (alkyl)(amino)carbenes (CAACs) are of great interest, as their electronic and steric properties provide a unique class of ligands and organocatalysts. Herein, substitution reactions involving novel carbonyl complexes of rhodium and nickel were studied to provide a deeper understanding of the fundamental electronic factors characterizing CAAC(methyl) , which were compared with the large array of data available for NHC and sterically more demanding CAAC ligands.
