In this research, a new magnetic core–shell nanocomposite Fe3O4@Sapogenin/Cu(II) based on quillaja sapogenin was prepared and The structure, magnetic features, and morphology of magnetic nanoparticles (MNPs) Fe3O4@Sapogenin/Cu(II) were studied totally via different experiments, such as energy-dispersive X-ray spectroscopy (EDS), thermogravimetric analysis (TGA), Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD), high-resolution transmissionelectron microscopy (HR-TEM), and Brunauer–Emmett–Teller (BET). vibrating sample magnetometer (VSM), scanning electron microscopy (SEM), inductively coupled plasma (ICP). The achievements demonstrated that the proposed agents were beneficial to synthesis the derivatives of β-aminoketone via a one-pot three-component reaction of ketones, aromatic aldehydes, and aromatic amines in ethanol under environmentally friendly conditions . The advantage of this reaction is the high efficiency of the products and the short reaction time. Furthermore, Fe3O4@Sapogenin/Cu(II) nanocatalyst can be easily recovered magnetically and can be reused for other runs without any reduction in the activity, also, with the use of this catalyst, several a novel products were obtained for the first time.
