Abstract
Synthesis of 5-substituted 1H-tetrazoles was achieved by [3+2] cycloaddition of nitriles and sodium azide in the presence of ammonium acetate. The reaction proceeds in situ formation of ammonium azide. Present protocol has advantage of good to excellent yields, short reaction times and simple isolation of products than reported methods.
