摘　　要：以咔唑基环铱二聚体与双齿咪唑盐反应,制备双齿氮杂环卡宾(NHCs)—咔唑基环铱化合物1-4,并对其结构进行表征.研究这类双齿NHCs—环铱化合物的发光性能和催化性能,发展NHCs—环铱化合物和钯盐共催化乙酰基二茂铁、2-氨基-5-溴苯甲醇和芳基硼酸偶联催化体系,提供一种“一锅法”制备二茂铁基喹啉联芳基衍生物的高效合成方法.New bidentate N-heterocyclic carbenes(NHCs)-cyclometalated iridium complexes bearing carbazole group 1-4 have been prepared from the bridge-splitting reaction of the corresponding dimers with imidazoliums and characterized by MS and NMR,respectively.The photoluminescence and catalytic properties of these complexes were investigated.An efficient NHCs-cyclometallated iridium/Pd(OAc)2 cocatalyzed three-component reaction of acetylferrocene,(2-amino-5-bromophenyl)methanol,and arylboronic acids has been developed.This protocol provides an efficient access to one-pot synthesis of 6-aryl-2-ferrocenylquinoline derivatives.
