In this dissertation, a novel magnetic nano-catalyst of Fe3O4@SiO2@Si(CH2)3NH@CC@Im@Co was synthesized. The synthesize catalyst was characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The functional groups on the surface’s catalyst were identified by Fourier transform infrared (FT-IR) spectroscopy. The thermal stability of the catalyst was studied by thermal gravimetric analysis (TGA). Then, the catalyst was used for multicomponent reactions including the synthesis of 2-amino-3-cyanopyridine and 1-(α-aminoalkyl)-2-naphthol derivatives. These derivatives were synthesized with high reaction yields and short time. All synthesized compounds were characterized using infrared spectroscopy and nuclear magnetic resonance (NMR). The major adventages of this catalyst include easy synthesis, easy separation, mild reaction temperature and solvent free condition. This catalyst can be recycled and used several times in a reaction with a slight drop in its efficiency and activity.
