Magnetic CuFe2O4/g-C3N4 hybrids were synthesized through a facile method and their catalytic performances were evaluated in click chemistry for the first time. The structural and morphological characterization of prepared materials was carried out by different techniques such as X-ray diffraction, high-resolution transmission electron microscopy, field emission scanning electron microscopy, Fourier infrared spectroscopy, vibrating sample magnetometry, thermogravimetric analysis, and N-2 adsorption-desorption analysis (Brunauer-Emmett-Teller surface area). The utilization of magnetic CuFe2O4/g-C3N4 enabled superior performance in the one-pot azide-alkyne cycloaddition reaction in water using alkyl halides and epoxides as azide precursors without the need of any additional agents. The present system is broad in scope and especially practical for the synthesis of macrocyclic triazoles and also tetrazoles. In addition, the catalytic system highly fulfills the demands of green click chemistry with its convenient conditions, especially easy access to a variety of significant products in low catalyst loading and simple work-up and isolation procedure.
