Summary:We herein reported the N-heterocyclic carbene-palladium( ii )-1-methylimidazole complex catalyzed direct C-H bond arylation of imidazo[1,2- a ]pyridines with aryl chlorides. Under suitable conditions, all reactions between various imidazo[1,2- a ]pyridines and aryl chlorides worked well to give the desired C3-H arylated products in acceptable to high yields, giving a convenient and alternative method for the direct C-H bond arylation of imidazo[1,2- a ]pyridines, using economic and easily available aryl chlorides as the arylating reagents. NHC-Pd( ii ) complex catalyzed C-H bond arylation of imidazo[1,2- a ]pyridines with aryl chlorides was reported.
