ABSTRACT

---

An environmentally friendly and efficient procedure has been developed for synthesis of β-amino carbonyls using a copper(II)-propyl amine immobilized on silica-coated Fe3O4 (Fe3O4@SiO2) nanoparticles as a novel and recyclable nanocomposite catalyst. The structure of this new magnetite nanocomposite catalyst was established by thermogravimetric analysis (TGA), FT-infrared spectroscopy (FT-IR), vibrating sample magnetometer (VSM), and X-ray diffraction (XRD) analysis. The catalyst could be recycled four times without much decrease of activity.
