A straightforward approach for the synthesis of alkyl 1H-tetrazol-5-yl thioethers from aldehydes and 1H-tetrazole-5-thiol through a one-pot procedure is presented. The aldehydes were first condensed with N-tosylhydrazine to generate the N-tosylhydrazones, which were then reductively coupled in situ with 1H-tetrazole-5-thiols under metal-free conditions to afford the thioethers in high to excellent yields.
