Research Article Synthesis of bis-thiazoles, bis-pyrazoles, bis-hydrazonates, and

Abstract: A facile synthesis of bis-thiazoles, bis-pyrazoles, and bis-hydrazonates from the reaction of bis-hydrazonoyl dichlorides with dierent moieties is described. Bis-triazolothiadiazoles were synthesized via oxidative cyclization of bis-hydrazones. Structures of the nal product were elucidated by elemental analyses and spectral data. Key words: Bis-hydrazonoyl, bis-thiazoles, bis-pyrazoles, bis-hydrazonates, bis-hydrazones 1
