An efficient and practical protocol for palladium-catalyzed direct C—H bond arylation of imidazo[1,2-a]pyridines with cheap aryl/heteroaryl chlorides has been developed. Various imidazo[1,2-a]pyridines with electron-neutral, electron-poor, electron-rich, even sterically hindered aryl chlorides and heteroaryl chlorides were successfully applied to the reaction in aqueous medium to achieve the 3-arylimidazo[1,2-a]pyridines in mostly good to excellent yields, thus representing a signi?- cant advancement in the implementation of the direct C—H bond arylation of imidazo[1,2-a]pyridines with aryl chlorides.

Key words: C-H bond arylation, imidazo[1,2-a]pyridines, 3-arylimidazo[1,2-a]pyridines, aryl/heteroaryl chlorides, aqueous medium
