Secondary amines react with cyanogen azide at ambient temperature in water/acetonitrile to provide tetrazole derivatives directly. The scope and limitations with regard to steric hindrance of the amine are discussed. Although reaction yields are moderate, 29–81 %, the cyanogen azide reactions provide a direct and versatile route to functionalized tetrazoles that may be especially useful considering the diversity of amines suitable for this transformation.
