金属酞菁配合物催化的咪唑N-芳基化反应

N-Arylation of Imidazole Catalyzed by Metal Phthalocyanine Complexes

使用钼酸铵催化法和DBU催化法分别合成α位和β位取代的金属酞菁配合物,并通过MS、元素分析、IR和UV-Vis对化合物结构进行表征.考察金属酞菁配合物上取代基的位置以及中心金属对咪唑N-芳基化反应的影响.研究结果表明α位取代的铜酞菁配合物具有更好的催化性能.

α-and β-substituted metal phthalocyanine complexes were prepared by using(NH 4) 2MoO 4 and DBU as catalysts respectively.Their structures were characterized by mass spectrum,elemental analysis,IR and UV-Vis spectra.The position of the substituents on metal phthalocyanine complexes and the effect of central metals on N-arylation of imidazole were studied.The results revealed that the copper phthalocyanine complexes substituted at α position have better catalytic performance.
