## 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
## Abstract New tricyclic 1,2,3‐triazolo‐1,2,4‐triazolo‐pyridazine derivatives, bearing a methyl substituent on the 1,2,3‐triazole ring, were prepared as potential biological agents. __N__‐Methylation of dimethyl 1,2,3‐triazole‐4,5‐dicarboxylate allowed synthesis of the isomeric 1‐methyl‐4,7‐dihydr
