Recyclable CuO nanoparticles were successfully employed to catalyze the microwave-assisted (3+2) cycloaddition reaction between nitriles and NaN₃ to efficiently synthesize 5-substituted 1H-tetrazoles. The salient features associated with this protocol are its cost effectiveness, rapid synthesis, stability, reusability, mild reaction conditions without any additives, high tolerance to various func-tional groups, and excellent yields under microwave irradiation. This environmentally friendly, microwave-assisted, nanoparticle-catalyzed synthetic methodology is seen as an alternative to conventional procedures that involve Lewis acid catalysts and a simple operation to the privileged scaffold.
