Palladium/Imidazolium Salts: A General and Highly Efficient Catalytic System for Coupling Reaction

摘要

@@ Nucleophilic N-heterocyclic carbenes have attracted considerable attention. These ligands are strong σ-donor with negligible π-accepting ability, and in this regard, they resemble electron-donor phosphines and can be addressed as "phosphine mimics". [ 1]
