Abstract

Fe (III) supported graphitic carbon nitride Nanocomposite was synthesized by impregnation of FeCl3 with g-C3N4 (Fe (III) @ g-C3N4). Then, the synthesis of Spirooxindole derivatives was carried out in the presence of Fe (III) @ graphitic carbon nitride Nanocomposite via the Multi-component reaction of malononitrile, isatins, and 1, 3-dicarbonyl compounds in green media (ethanol/water (1: 1)) under reflux conditions and the corresponding products were prepared in good to excellent yields (70-98 %). Also, the heterogeneous nanocatalyst was characterized by different techniques including the transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR), thermal gravimetric analysis (TGA), atomic absorption spectroscopy (AAS) and X-ray diffraction (XRD). Furthermore, the Nanocomposite is recoverable and reusable several times without a negligible decrease in its catalytic performance.
