A study was conducted to investigate the presence of iron salts in the catalyzed synthesis of 5-substituted 1H-tetrazoles. Para-trifluorotoluonitrile and trimethylsilyl azide were selected as model substrates for the initial metal source screening and the optimization of the reaction conditions. It was observed that the catalysis proceeded successfully producing tetrazole in 91% yield. A screening of various iron salts revealed that both the oxidation state of the iron and the counterion had a minor effect on the catalysis. Iron sources with different purity grades obtained from various providers were applied to investigate that the catalysis was not resulting from trace impurities in the metal salt. It was also observed that the catalysis proceeded successfully for a wide variety of aryl nitriles, providing tetrazoles in high yields. The best catalysis results were achieved with compounds that contained electron-withdrawing groups.
