A series of 5-substituted 1H-tetrazoles I (R = 4-O2NC6H4, 4-BrC6H4, 4-MeC6H4, etc.) were synthesized in DMF by the [3 + 2] cycloaddition reaction under the effect of microwave irradiation (10-30 min, fixed mode, 90 °C, 140 W) in the presence of highly efficient superior catalyst. For this reaction, different aromatic nitriles with the sodium azide were used and superior monodisperse (Md) platinum nanoparticles (Pt NPs) decorated on activated carbon (AC) served as a catalyst. Md-Pt NPs@AC were reproducibly and easily produced by double solvent reduction of PtCl4 in room temperature and characterized by transmission electron microscopy (TEM), the high resolution electron micrograph (HRTEM), X-ray diffraction (XRD), at. force microscopy (AFM) and XPS. The sum of their results shows the formation of highly crystalline and colloidally stable Md-Pt NPs@AC. The catalytic performance of these new NPs were investigated for the synthesis of 5-substituted 1H-tetrazoles, in which they were found to be exceptional reusable, isolable, stable and highly efficient heterogeneous catalyst.
