Two [1,2,4]triazolo[4,3-b]tetrazines were synthesised and alkylated using various reagents. The formation of the ethylated [1,2,4]triazolo[4,3-b]tetrazinium salts and their structure was unambiguously established using correlational NMR spectroscopy. The product distribution was interpreted on the basis of quantum chemical calculations. The triazolotetrazinium salts were found to dealkylate on workup to give the corresponding tetrafluoroborate salts.
