ChemInform Abstract: N-Heterocyclic Carbene Ligands Bearing Poly(ethylene Glycol) Chains: Effect of the Chain Length on Palladium-Catalyzed Coupling Reactions Employing Aryl Chlorides

N-Heterocyclic carbenes bearing poly(ethylene glycol) chains of different lengths have been designed and employed as ligands in palladium-catalyzed coupling reactions. The catalyst system having longer chains was found to be highly efficient for Suzuki–Miyaura coupling and borylation reactions employing aryl chlorides under mild reaction conditions.
