Synthesis of spirooxindole derivatives catalyzed by Fe (III)@graphitic carbon nitride nanocomposite via one-pot multi-component reaction

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 nanocompositevia the multi-component reaction of malononitrile, isatins, and 1,3...
