摘要： 通过简单的离子交换法制备出蒙脱土 (MMT) 负载 Cu+催化剂, 采用 X 射线衍射, X 射线光电子能谱, 扫描电子显微镜和 X 射线能量色散谱等技术对催化剂样品进行了表征. 结果表明, Cu+已经成功的插入到蒙脱土层间. 在芳基氯或芳基溴与含氮杂环化合物的 N-芳基化反应中, 催化剂显示出高的催化活性, 且可通过简单的过滤分离出该催化剂, 重复使用 4 次其活性无明显降低.

Abstract: Montmorillonite-supported copper (I) catalyst has been prepared by a simple ion exchange method. The resulting catalyst was characterized by X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy, and energy dispersive X-ray spectrometry, with results showing that Cu+ had been successfully intercalated into the interlayer of Montmorillonite. The catalyst showed high levels of activity towards the N-arylation of nitrogen heterocycles with aryl chlorides or bromides. Furthermore, the catalyst could be reused up to four times without any significant loss in activity.

Key words: copper, montmorillonite, N-arylation reaction, aryl halides, heterogeneous catalyst
