چکیده	Reactions of CoFe2O4 magnetic nanoparticles supported ligands, 2-amino-2-methyl- 1,3-propanediol (Amino glycol), with cerium salts provided the respective anchored complex CoFe2O4 @Amino glycol/Ce. The nanocatalyst was characterized perfectly using thermogravimetric analyses, FT-IR spectroscopy, scanning electron microscopy, energy-dispersive X-ray inductively coupled plasma optical emission spectroscopy vibrational sample magnetometry and powder X-ray diffraction. CoFe2O4 magnetic nanoparticles supported ligands with cerium salts afforded active catalysts for the synthesis of 5-substituted 1H-tetrazoles and oxidation of sulfides at mild reaction conditions in the green medium under optimized conditions. The ligand and metal atom identity influenced the catalytic activity of the nanocatalyst. The immobilized complexes were easily collected via an external magnetic field and further reused at least 6 times without significant loss of catalytic activity and selectivity.
