Abstract
A new and rapid synthetic method of diaryl carbazone (ArN=NCONHNHAr) from a ryl substituted carbazide is reported for the first time. Eight of the comp ounds were prepared by oxidation of aryl substituted carbazide using N-Brom osuccinimide and pyridine as the oxidation system in good yield under mild condition. This method only need simple instrument and short reaction time. A possible mechanism is suggested.
