In the study, magnetic nanoparticles (MNPs) of the immobilized SbFx species on copper or nickel ferrite as CuFe2O4@SbFx and NiFe2O4@SbFx were synthesized. Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), vibrating sample magnetometer (VSM), Brunauer-Emmett-Teller (BET) analysis and inductively coupled plasma optical emission spectroscopy (ICP-OES) were employed to characterize the prepared nanocatalysts. Catalytic activity of the naomaterials was more studied towards reduction and reductive acetylation of structurally diverse aromatic nitro compounds as well as acetylation of arylamines. Among the examined nanocatalyst systems, CuFe2O4@SbFx was used for reduction and reductive acetylation of aromatic nitro compounds, whereas, NiFe2O4@SbFx showed an activity towards acetlyaltion of arylamines. All reactions were carried out successfully in H2O as a green solvent under reflux conditions. After completion of the reactions, the examined nanocatalysts were easily removed from the reactions mixture by an external magnetic field. Their reusability was also examined for 5 consecutive cycles without the significant loss of the catalytic activity.
