Then, the synthesis of spirooxindole derivatives was carried out in the presence of Fe (III) @ graphitic carbon nitride nanocompositevia 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.}, number={2}, journal={Iranian Journal of Catalysis}, publisher={OICC Press}, author={Allahresani, Ali and Taheri, Bahare and Nasseri, Mohammad Ali}, year={2024}, month={Feb.}, keywords={Nanocomposite, Multi-component reaction, Graphitic carbon-nitride, Spirooxindole derivatives} }
