چکیده مقاله :
Recently, the development of new catalysts to promote organic reactions has become an integral part of research plans [1,2]. In this research, the catalytic behavior of COF@ZnFe2O4 composite was explored in the preparation of by a one-three-component reaction of benzaldehydew, dimdone, and phenylenediamine .COF@ZnFe2O4 is introduced as a new catalyst with high efficiency for the synthesis of benzodiazepines. The structure of the synthesized materials was elucidated using various spectral techniques such as: X-ray crystallography (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX/Mapping), Fourier transform infrared (FTIR), Brunauer-Emmett-Teller (BET), The present method brought several advantages, including: short reaction times, high yield of products, high catalytic activity and high thermal stability
