Zinc complex with 2-amino-3-hydroxy-pyridine ligand was immobilized onto chloropropyl-modifed mesoporous silica MCM-41 (CP-MCM-41) via post-grafting method. The prepared catalyst has been characterized by low-angle X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, energydispersive spectrum, atomic adsorption spectroscopy and thermogravimetric analysis. The immobilized nano-structured material showed very good catalytic activity and excellent recycling effciencies for the oxidation reaction of sulfdes to sulfoxides and oxidative coupling of thiols to their corresponding disulfdes in the presence of aqueous hydrogen peroxide as oxidant at room temperature and the synthesis of 2,3-dihydroquinazolin-4(1H)-one derivatives in water.
