Synthesis of bis-thiazoles, bis-pyrazoles, bis-hydrazonates, and bis-triazolothiadiazoles based on bis-hydrazonoyl and bis-hydrazones


Abstract: A facile synthesis of bis-thiazoles, bis-pyrazoles, and bis-hydrazonates from the reaction of bis-hydrazonoyl dichlorides with different moieties is described. Bis-triazolothiadiazoles were synthesized via oxidative cyclization of bis-hydrazones. Structures of the final product were elucidated by elemental analyses and spectral data.

Keywords: Bis-hydrazonoyl, bis-thiazoles, bis-pyrazoles, bis-hydrazonates, bis-hydrazones
