Chemistry of 1,2,4-Triazines; XIII. Synthesis of 1H-[1,2,4]Triazino [5,6-e][1,3,4]thiadiazines and 1,2,4-Triazolo[4,3-d][1,2,4]triazines The reaction of 6-amino-5-hydrazino-1,2,4-triazines with (thioacylthio)acetic acids affords 6-amino-5-(N 2-thioacylhydrazino)-1,2,4-triazines while the reaction with ethyl dithioacetate yields 8-amino-1,2,4-triazolo[4,3-d] [1,2,4]triazines. The 6-amino-5-(N 2-thioacylhydrazino)-1,2,4-triazines cyclize in aqueous mineral acid to give 1H-[1,2,4]triazino [5,6-e] [1,3,4]thiadiazines. Some further reactions of 5-hydrazino-1,2,4-triazines are reported.
