A simple and efficient method for the preparation of 5-aryl 1-H-tetrazoles was developed from various aryl nitriles and sodium azide (NaN3) via [3+2] cycloaddition reaction using activated Fuller’s earth as an efficient heterogeneous catalyst. This catalyst has advantageous of cost, stability, recovery, reusability, and ecological benefits along with high product yield, and mild protocol.

@ Tris (hydroxymethyl)aminomethane‐Cu(I): a novel, highly efficient and reusable nanocatalyst for the C‐C bond formation and the synthesis of 5‐substituted 1H‐tetrazoles in green media
In this work, a versatile protocol was introduced for the preparation of a newCu(I) supported complex on Silica supported boehmite nanoparticles (Boehmite@SiO2@Tris‐Cu(I)). The structure of the catalyst was comprehensively characterized using Fourier transform infrared spectroscopy (FT‐IR), X‐Ray Diffractometer (XRD), energy‐dispersive X‐ray spectroscopy (EDS), inductively coupled plasma atomic emission
