Fe۳O۴@SiO۲@۲-Aminothiophenol-Cu: a novel magnetically reusable nanostructuredcatalyst for the efficient synthesis of ۲,۳-dihydroquinazolin-۴(۱H)-ones

Fe۳O۴@SiO۲@۲-Aminothiophenol-Cu demonstrates its capability as a reusable and heterogeneouscatalyst in the efficient synthesis of various ۲,۳-dihydroquinazolin-۴(۱H)-one derivatives through the twocomponentcondensation of ۲-aminobenzamide and an aldehyde. This reaction offers simplicity, environmentalfriendliness, and cost-effectiveness. The catalyst can be easily separated and recycled by employing magneticdecantation with the assistance of an external magnet. The characterization of the catalyst was performed usingFESEM, EDS, TGA, VSM, and X-ray diffraction techniques
