The first report on the eco-friendly synthesis of 5-substituted 1H-tetrazoles in PEG catalyzed by Cu(ii) immobilized on Fe₃O₄@SiO₂@l-arginine as a novel, recyclable and non-corrosive catalyst

Cu(ii) immobilized on Fe₃O₄@SiO₂@l-arginine as a novel nanostructured compound catalyzed the cycloaddition reaction of organic nitriles and sodium azide to produce 5-substituted 1H-tetrazoles.
