Synthesis of bipyrazole and 1,3,4-thiadiazole derivatives

Synthesis of bipyrazole and 1,3,4-thiadiazole derivatives

New hydrazonoyl bromides reacted with several C-nucleophiles to give the corresponding bipyrazoles. Treatment of 3-cyanoacetylpyrazole derivatives with phenyl isothiocyanate in potassium hydroxide followed by hydrazonoyl bromides gave the corresponding pyrazolyl-1,3,4-thiadiazoles.
