| Abstract: | A number of new 1,2,4]triazolo4,3‐b]pyridazines were prepared by either cyclocondesation of substituted hydrazinopyridazines with orthoesters or oxidative cyclization of their hydrazone analogs in nitrobenzene as an oxidizing agent. A host of other new 1,2,4]triazolo4,3‐b]pyridazine derivatives were synthesized by sequential treatment of the latter compounds with carbon disulfide and alkyl halides. |
