The intramolecular cyclization of (6-R-1,2,4,5-tetrazin-3-yl)hydrazones of ketones (R is 3,5-dimethylpyrazol-1-yl, 4-methylimidazol-1-yl, or 2-alkylidenehydrazino) giving rise to the previously unknown ,7-dihydro-1,2,4-triazolo[4,3-b]-1,2,4,5-tetrazines, including spiro com-pounds, was studied. The reactivity and the yields of the reaction products depend on the structure of the alkylidene fragment and the nature of the substituent in the tetrazine ring. ; 2009 Springer Science+Business Media, Inc.
