HPA-ZSM-5 nanocomposite as a highly effective and easily retrievable catalyst for the synthesis of furans

Abstract

HPA-ZSM-5 nanocomposite as a green heterogeneous catalyst was utilized for the synthesis of furans by the three-component reaction of phenylglyoxal, dimethyl acetylenedicarboxylate and primary amines. The best results were obtained in the presence of 6 mg of HPA-ZSM-5 nanocomposite in CH2Cl2 at room temperature. The zeolite catalyst has been characterized by X-ray diffraction (XRD), field emission scanning electron microscopes (FE-SEM), energy dispersive spectroscopy (EDS), Fourier transform infrared (FT-IR), and N2-adsorption analysis. Experimental simplicity, wide range of products, excellent yields in short reaction times, reusability of the catalyst, and low catalyst loading are some of the substantial features of this method.
