Synthesis of novel bis-thiadiazoles, bis-triazoles and polypyrazole derivatives based on hydrazonoyl halides

A series of novel bis-thiadiazoles and bis-triazoles derivatives were synthesized via the reaction of hydrazonoyl halides with different moieties. Also, the synthesis and mechanism for polypyrazole formation are described via reaction of bis-hydrazonoyl with p-benzoquinone. Synthesized compounds were elucidated by elemental analysis and spectral data.
