【摘要】 研究了氧化还原石墨烯负载铜(Cu-rGO)催化的咪唑N-芳基化反应.催化剂进行了红外光谱(IR),X-射线单晶衍射(XRD),X-射线光电子能谱(XPS)等表征.研究结果表明,该催化剂具有高的催化活性,仅使用0.5mol%量的催化剂对反应就具有高的催化效率.催化剂可以循环使用3次没有大的活性下降,且通用性好.更多还原

【Abstract】 An efficient catalytic system for N-arylation reactions on heterogeneous copper reduced Graphene based catalyst(Cu-rGO) was described. The as-prepared catalyst was characterized by a variety of techniques,including Fourier transform infrared spectroscopy(FT-IR),X-ray photoelectron spectroscopy(XPS),X-ray diffraction(XRD),etc. The results showed that the high activity was obtained by low dosage of catalyst,and 0. 5 mol% of the catalyst was sufficient. The catalyst could be reused for 3 times without significant loss in activity,and also showed high catalytic activity with a wide variety of substituents.更多还原
