Nano-silica sulfuric acid as a heterogeneous, eco-friendly and reusable catalyst was used in the synthesis of 1,3,5-triarylbenzenes via triple-self condensation of acetophenones. All reactions were performed under solvent-free conditions and microwave irradiation. Short reaction times, high yields, easy isolation and purification of products and good reusability of this catalyst are the mainspring to choose for the preparation of 1,3,5-triarylbenzenes.
纳米二氧化硅硫酸作为异相、环保且可重复使用的催化剂,被用于通过乙酰苯的三重自缩合反应合成1,3,5-三芳基苯。所有反应均在无溶剂条件和微波辐射下进行。短反应时间、高产率、产品易于分离和纯化以及该催化剂的良好重复性是制备1,3,5-三芳基苯选择这种催化剂的主要原因。
