Abstract

A heterogeneous solid acid catalyst, sulfonic acid supported on pericarp-pomegranate (sulfonic acid@PP) is prepared with green an eco-friendly approach. The prepared sulfonic acid@PP catalyst was extensively characterized by IR, FE-SEM, EDX and TGA techniques. The efficiency of the catalyst has been investigated for the synthesis of bis(indolyl)alkanes by electrophilic substitution reaction of indoles with carbonyl compounds in ethanol at 80 oC. Easy recovery by simple filtration and at least three times reusability without significant loss in the yield of the desired product are conspicuous features of the reported catalyst. In addition, the notable features of this protocol are high conversions, shorter reaction times, cleaner reaction profile, simple experimental and work-up procedure.

磺酸@果皮-石榴:天然负载型催化剂,用于合成双(吲哚基)烷烃

摘要

采用绿色环保的方法制备了多相固体酸催化剂,即负载在果皮-石榴上的磺酸(磺酸@PP)。所制备的磺酸@PP催化剂通过IR,FE-SEM,EDX和TGA技术进行了广泛表征。已经研究了催化剂在80 o C下通过吲哚与羰基化合物在乙醇中的亲电取代反应合成双(吲哚基)烷烃的效率。通过简单过滤即可轻松回收,并且至少可重复使用三遍,而收率没有明显损失所需产物的特征是所报道的催化剂的显着特征。另外,该方案的显着特征是高转化率,较短的反应时间,更清洁的反应曲线,简单的实验和后处理程序。
