Synthesis of 3,3′-bi-1,2,4-Triazolo[4,5-a]- benzimidazole, 5,5′-bi-1,3,4-Thiadiazole, and Thiazolo[3,2-a]benzimidazole Derivatives
摘要:
A series of novel 3,3′-bi-1,2,4-triazolo[4,5-a]benzimidazole and thiazolo[3,2-a]-benzimidazole derivatives were synthesized via the reaction of bis-hydrazonoyl chlorides with 2-methylthiobenzimidazole and with benzimidazol-2-thiol, respectively. A direct synthesis of 5,5′-bi-1,3,4-thiadiazole and 4,5-bis-phenylhydrazono-2,3,4,5-tetrahydrothiazole derivatives is also described.
