, (2021/10/12)
An efficiently, magnetically retrievable Fe3O4@SiO2@NH2@Pd(OCOCH3)2 nanoparticles was successfully synthesized and affirmed by several physicochemical characterization tools, such as scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy-disoersive X-ray spectroscopy (EDX), Fourier-transform infrared spectroscopy (FT-IR), and power X-ray diffraction. Thereafter, the catalytic performance of this environmentally benign nanocatalyst was investigated in the one-pot multicomponent synthesis of biologically important 2-amino-3-cyano-4H-pyran, tetrahydro-4H-chromenes and spiro2-oxindole derivatives. The reaction was simply achieved via one-pot three-component reaction of arylaldehydes, malononitrile and dimedone/isatins/methylaceto acetate ethanol at room temperature, with excellent yields and high purity. A new catalytic system, recyclability of reaction medium, little reaction times and excellent yields with easy workup render this protocol more attractive and economically viable.
