Synthesis and Characterization of a Novel and Reusable Adenine Based Acidic Nanomagnetic Catalyst and Its Application in the Preparation of 2-Substituted-2,3-dihydro -1H-perimidines under Ultrasonic Irradiation and Solvent-Free Condition

Abstract

In this study, a novel and reusable adenine-based nano magnetic catalyst namely Fe₃O₄@SiO₂@(CH₂)₃NHCO-adenine sulfonic acid was designed and synthesized. The structure of the titled catalyst was fully characterized using several skills including FT‐IR spectroscopy, X‐ray (EDX) analysis, X‐ray diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission electron microscopy (TEM), Thermal Gravimetric Analysis (TGA), and Vibrating-Sample Magnetometer (VSM). Then, the catalytic performance of Fe₃O₄@SiO₂@(CH₂)₃NHCO-adenine sulfonic acid was subjected toward the synthesis of 2,3-dihydro-2-aryl-1H-perimidines using 1,8-diamino naphthalene and aryl aldehydes under ultrasonic irradiation and solvent-free condition. Also, some new compounds of perimidines were synthesized in the presence of this catalyst, and the catalyst has been shown high potent of recovering and reusing capability.
