摘要

A simple N-acylimidazolium salt precursor to a NHC-complexed palladacyclic ligand gives high turnover numbers (> 107) for Suzuki–Miyaura coupling and is applied to the preparation of biaryls used in the synthesis of coumarins. The results suggest that N-acyl- NHC derivatives can contribute to further expanding the rich chemistry of NHCs.
