Abstract

A new and regioselective nanocatalyst (Fe3O4@S-TiO2/Cu) was synthesized by the solvothermal method. In this research, sulfur heteroatoms were doped on Fe3O4@TiO2 substrate and used as a ligand to stabilize copper nanoparticles without using organic linker. Fe3O4@S-TiO2/Cu nanorods were successfully synthesized and characterized using the FT-IR, ICP, PXRD, SEM, TEM, EDX, EDX-mapping, VSM, TGA, and BET techniques. Also, its catalytic activity was evaluated in preparing various triazole derivatives. 1,4-Disubstituted 1,2,3-triazole derivatives prepared from one-pot three-component condensation of epoxides/halides, phenylacetylene/ propargyl esters, and sodium azide using Fe3O4@S-TiO2/Cu as a novel and reusable heterogeneous nanocatalyst. High regioselectivity and compound yields, short reaction times, high and easy separation of the catalyst by an external magnet from the reaction mixture and simple workup are considerable advantages of this nanocatalyst. In addition, this nanocatalyst could easily be recycled and used six times without decrease in initial catalytic activity.
