In this work firstly Fe2O3 nanoparticles were synthesized via a simple chemical method. Properties of the product were examined by X-ray diffraction pattern (XRD), Scanning electron microscope (SEM) and Fourier transform infrared (FT-IR) spectroscopy. Vibrating sample magnetometer (VSM) shows nanoparticles exhibit ferromagnetic behavior. To continue some of the 2-naphthol condensed 1,3-oxazinone derivatives employing one-pot condensation reaction in the presence of Fe2O3 nanoparticles as an acid catalyst were described. The present methodology offers several advantages, viz. high yields, clean reaction, short reaction times, recyclability of the catalyst and simple workup procedure.
