Abstract

The [3+2] cycloaddition between various nitriles and trimethylsilyl azide proceeds smoothly in the presence of a CuI 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 azide species, followed by a successive [3+2] cycloaddition with the nitriles.
