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.
易于获取和处理的醚-咪唑啉氯化物被开发为配体前体。杂芳基氯化物与芳基/杂芳基硼酸和酯的偶联反应由钯/醚-咪唑啉氯化物体系催化，对底物具有高耐受性，以良好至优异的收率得到各种杂联芳烃。
