Synthesis and characterization of some new benzodiazepinium salt derivatives under microwave irradiation

Abstract EN

An attempt to synthesize the benzoimidazol derivatives from the reaction of o-phenylenediamine and benzoic acid derivatives in the presence of ethanol and various ketones under microwave irradiation, 1 , 5 - benzodiazepinum salt derivatives were obtained instead of them.

Unexpected reaction was happened for synthesis a new series of benzodiazepinium salt derivatives in a selective yield .

The reaction mechanism was also discussed.

The new compounds were purified and identified their structures were elucidated using various physical techniques like; FT- IR spectra, micro elemental analysis (C.H.N) and 1H NMR spectra.
