Various di- and trisubstituted (benzotriazolyl)carboximidamides were used for the preparation of N,N-di- and 1,N,N-trisubstituted 5-aminotetrazoles 3a-e and 6a-d under mild conditions in good to excellent yields.

The addition of sodium azide to nitriles to give 1H-tetrazoles is shown to proceed readily in water with zinc salts as catalysts. The scope of the reaction is quite broad; a variety of aromatic nitriles, activated and unactivated alkyl nitriles, substituted vinyl nitriles, thiocyanates, and cyanamides have all been shown to be viable substrates for this reaction.
