可循环疏水性铜酞菁催化咪唑的N-芳基化反应

Recyclable hydrophobic copper(Ⅱ) phthalocyanine catalyzed N-arylation of imidazoles in dimethylsulfoxide

研究了二价铜酞菁(CuPc)催化咪唑与芳基碘或溴的N-芳基化反应.结果表明,CuPc表现出高的催化活性,并且能够重复使用3次活性无明显降低.采用傅里叶变换红外光谱、X射线光电子能谱和紫外-可见光谱对催化剂样品进行了表征.

Copper （II） phthalocyanine （CuPc） was used as a catalyst for the N-arylation of imidazoles with aryl iodides or bromides. The catalyst showed high activity and could be reused 3 times without any significant loss in activity. The catalyst was characterized by Fourier transform infrared spectros-copy, X-ray photoelectron spectroscopy, and ultraviolet-visible spectroscopy.
