Abstract: | Some new 1,2,3-triazolo4,5-d]-1,2,4-triazolo4,3-b]pyridazines were prepared starting from the corresponding 1,2,3-triazolo4,5-d]pyridazines via the formation of the 1,2,4-triazole ring, by condensation of an appropriate monocarbon fragment with the 4-hydrazino substituent and the nitrogen atom in the 5 position of the heterocycle. Condensation of 4-phenylhydrazino substituted derivatives with formic acid gave zwitterionic compounds. |
