Reaction of 2-hydrazinobenzimidazole with β-diketones: A structural reinvestigation

The reaction of 2-hydrazinobenzimidazole (1) with pentane-2,4-dione yields a pyrazole derivative (2) instead of the reported triazepine (3).Several 2-pyrazolylbenzimidazoles (4) have similarly been synthesized using unsymmetrical β-diketones and their precursors.It has been shown that 1H NMR spectroscopy can easily distinguish the isomeric pairs.
