| Abstract: | In this paper all efforts have been devoted to develop stabilized tannic acid-SO3H on Fe3O4@SiO2 nanoparticles as the new magnetically and eco-friendly nanocatalyst. This nanocatalyst was identified using different techniques such as fourier transform infrared (FT-IR), Powder X-ray diffraction (XRD), vibrating sample magnetometry (VSM), scanning electron microscopy (SEM), energy dispersive x-ray spectroscopy (EDXS) and thermogravimetric analysis (TGA). Catalytic performance of the catalyst in cyclocondensation reaction of anthranilamide with different aldehydes under the friendly environmentally reaction condition led to formation corresponding 2,3-dihydro-4(1H)-quinazolinones compounds in excellent yields. The catalyst could be easily recovered by an external magnet and reused 4 times without significant loss of catalytic activity. |
