with silver oxide followed by [Cp∗MCl2]2 (M = Ir, Rh), binuclear iridium and rhodium complexes 2 were formed. Reaction of these complexes 2 with AgPF6 afforded Cl-bridged cationic binuclear iridium and rhodium complexes 3. X-ray crystallographic analysis of 3 revealed that the two imidazole rings of the carbene ligand are in a parallel geometry. The cationic binuclear iridium complexes 3-Ir could be
通过1,8-二溴甲基萘与N-烷基咪唑的反应合成了新的甲基萘连接的咪唑鎓盐1。用氧化银接着用[Cp * MCl 2 ] 2(M = Ir,Rh)处理咪唑鎓盐1,形成双核铱和铑络合物2。这些配合物2与AgPF 6的反应得到Cl桥联的阳离子双核铱和铑配合物3。X-射线晶体学分析3显示,卡宾配体的两个咪唑环处于平行几何形状。阳离子双核铱配合物3-Ir 可用于2-乙炔基苯胺的分子内加氢胺化反应,得到相应的吲哚化合物。
