Abstract

The present paper shows the preparation of a highly porous periodic mesoporous organosilica (PMO) including the ionic liquid pore walls that supported with zinc ions onto PMO-IL (Zn@PMO-IL). Moreover, the material was characterized using field emission‐scanning electron microscopy, transmission electron microscopy, inductively coupled plasma, and N₂ adsorption–desorption. Likewise, the catalytic activity of the Zn@PMO-IL, illustrating a highly efficient nanocatalyst for the synthesis of propargylamines through three-component A³-coupling reaction of various aldehydes, amines, and arylacetylene. The results demonstrate an eco-friendly and appealing method with high efficiency and facile work-up procedure. Furthermore, the nanocatalyst can be revived by a simple filtration process and reuse at least five successive runs without considerable reducing in its activity.

离子液体基周期性介孔有机硅（Zn @ PMO-IL）上锌的合成，表征和应用在3-炔丙基胺合成反应中

摘要

本文显示了一种高度多孔的周期性介孔有机二氧化硅（PMO）的制备，该有机二氧化硅包括被锌离子支撑在PMO-IL（Zn @ PMO-IL）上的离子液体孔壁。此外，使用场发射扫描电子显微镜，透射电子显微镜，电感耦合等离子体和N ₂吸附-脱附对材料进行了表征。同样，Zn @ PMO-IL的催化活性说明了通过三组分A ³合成炔丙基胺的高效纳米催化剂-各种醛，胺和芳基乙炔的偶联反应。结果证明了一种高效，简便的后处理方法，一种环保且有吸引力的方法。此外，可以通过简单的过滤过程使纳米催化剂恢复活力，并且可以在不显着降低其活性的情况下重复使用至少五次连续运行。
