The [3+2] cycloaddition between various nitriles and trimethylsilyl azide proceeds smoothly in the presence of a Cu I catalyst in DMF/ MeOH, to give the corresponding 5-substituted 1H-tetrazoles in good to high yields. The reaction most probably proceeds through the in situ formation of a copper azi
