Abstract Triazolino[4,3‐a]pyrimidines pyrazolo[3,4‐d]pyridazines and isoxazolo[3,4‐d]pyridazines were synthesized from hydrazonoyl halides. Also, 3‐aminothieno[2,3‐b]pyridines and pyrimidino[4′,5′:4,5]thieno[2,3‐b]pyridines were synthesized from cynothioacetamide. Structures of the newly synthesized compounds were established on the basis of elemental analyses and spectral data.
