In an attempt to discover bicyclic compounds containing the 1,2,1,2,2,4-triazine-5-thiones from one pot reaction of arylnitriles with 4-amino-1,2,4-triazine-3-thione-5-one in the presence of potassium tert-butoxide were synthesized.
## Abstract Some new 1,2,3‐triazolo[4,5‐__d__]‐1,2,4‐triazolo[4,3‐b]pyridazines were prepared starting from the corresponding 1,2,3‐triazolo[4,5‐__d__]pyridazines __via__ the formation of the 1,2,4‐triazole ring, by condensation of an appropriate monocarbon fragment with the 4‐hydrazino substituent
