1-substituted-1H-tetrazole analogues 4(a–o) were synthesized, which were typically accessed via a facile, solvent-free and green synthetic protocol. The reaction involves expeditious reusable catalyst (SiO2–H3BO3) promoted condensation between a variety of heterocyclic/aromatic amines, sodium azide and triethyl ortho-formate, eliminating the use of an environmentally toxic solvent. This new eco-friendly and sustainable
