title: Ether-imidazolium carbenes for Suzuki-Miyaura cross-coupling of heteroaryl chlorides with aryl/heteroarylboron reagents.
abstract: Easily accessible and handled ether-imidazolium chlorides were developed as ligand precursors. The coupling reactions of heteroaryl chlorides with aryl/heteroarylboronic acids and esters were catalyzed by the palladium/ether-imidazolium chloride system with high substrate tolerance to give various heterobiaryls in good to excellent yields.
