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