Complexation of 1,8-naphthyridine(Np)-2-carboxylic derivatives L¹-L³ [L¹ = Np-2-COOH, L² = Np-2-CONH₂, L³ = Np-2-CONHCH₂Py] with [Ir(COD)(µ-OMe)]₂ yielded the corresponding complexes [Ir(COD)(Lⁿ)] (1~3, n = 1~3, respectively). The potential tridentate L³ behaves as a bidentate donor in the complex 3. Treatment of L¹ with [Ir(COD)Cl]₂ under nitrogen atmosphere gave a Ir(III) hydride complex [Ir(COD)(L¹)HCl] (4). However, carrying out the reaction in the presence of oxygen rendered a Ir(III) dichloride species [Ir(COD)(L¹)Cl₂] (5). All these complexes were characterized by spectroscopic analyses and X-ray single crystal determination. Catalytic activity of iridium complexes in amination of amines with alcohols was screened. It appears that iridium amido complexes 2 and 3 show excellent catalytic activity on amination of anilines with alcohols in the presence of Cs₂CO₃ at 120 °C.

1,8-萘啶（Np）-2-羧酸衍生物L ¹ -L ³ [ L ¹  = Np-2-COOH，L ²  = Np-2-CONH ₂，L ³  = Np-2-CONHCH ₂ Py ]用的[Ir（COD）（μ-OME）] ₂得到相应的配合物的[Ir（COD）（大号^ñ）]（1〜3中，n = 1〜3，分别地）。潜在的三齿大号^3个表现为在复杂的二齿供体3。用[Ir（COD）Cl] ₂处理L ¹在氮气氛下，得到Ir（III）氢化物络合物[Ir（COD）（L ¹）HCl]（4）。然而，在氧气存在下进行反应产生了二氯化Ir（III）物质[Ir（COD）（L ¹）Cl ₂ ]（5）。所有这些配合物均通过光谱分析和X射线单晶测定进行表征。筛选了铱络合物在胺与醇的胺化反应中的催化活性。似乎在120℃下，在Cs ₂ CO ₃存在下，铱酰胺基络合物2和3对苯胺与醇的胺化表现出优异的催化活性。
