咪唑及其衍生物是构建配位化合物的优良配体 [1]。这类配合物在功能材料领域 (磁学、非线性光学、催化性能) 有着潜在的应用价值 [2]。本文合成了一个咪唑衍生物：1-(苯并三氮唑-1-甲基)-1-(2-甲基咪唑) ，用该化合物作为配体与过渡金属盐反应，得到了四个金属配合物，[Zn(bmmi)4]·2NO3 (1) ，[Cd (bmmi)(SO4)(2CH3OH)(H2O)]n (2) ，{[Ag(bmmi)]·NO3}n (3) ，{[Cu(bmmi)(N3)(NO3)]·CH3OH}n (4) [bmmi = 1-(苯并三氮唑-1-甲基)-1-(2-甲基咪唑)]。其中配合物 4 对2,6-二甲基苯酚氧化偶联反应具有良好的催化活性。

A new compound based imidazole, 1-((benzotriazol-1-yl)methyl)-1-H-1,3-(2-methyl-imdazol) (bmmi), was synthesized. Using it as ligand to react with the transition metal salts, we obtained four complexes (1 – 4). Complex 4 was tested as catalysts in the environmental friendly aqueous-medium process of the oxidative coupling of 2,6-dimethylphenol (DMP). Under the optimized reaction conditions, the complex is catalytically active and exhibits high performance.
