Tetrazoles have found use in various sciences, including photography and information recording systems [1,2]. Conventional procedure for synthesis of 5‐substituted 1H–tetrazoles is [3 + 2] cycloaddition of azides to the corresponding nitriles. Based on this method, several methode have been reported [3, 4]. In this work, a green method is reported for homoselective synthesis of biologically active tetrazole derivatives in the presence of Cu@SBA-15 catalyst. The tetrazole derivatives was performed in green solvents in the presence of this catalyst. All products were obtained in high turnover frequency numbers and good yields in the presence of this catalyst, which revelved the high efficiency and catalytic activity of this catalyst. Cu@SBA-15 catalyst was characterized by BET, XRD, TGA, FT-IR, SEM, EDS, WDX, and AAS. This catalyst can be recovered and reused for several runs without significant change in its catalytic activity.
