An efficient route for the synthesis of 5-substituted 1H-tetrazole via [2+3] cycloaddition of nitriles and sodium azide is reported using γ-Fe2O3 nanoparticles as a magnetic separable catalyst. Under optimized conditions, the moderate to good yields (71-95%) can be obtained. The catalyst can be easily separated by a magnet and reused for several circles.
