Abstract : The reductive coupling of several nitrobenzenes by zinc/sodium hydroxide followed by acetylation of the resulting hydrazobenzenes with pyridine/acetic anhydride produced n-acetylhydrazobenzenes. Treatment of the n-acetylhydrazobenzenes with concentrated hydrochloric acid produced a series of n-acetylalkylbenzidines. These were further acetylated with pyridine/acetic anhydride to produce N,N'-diacetylalkylbenzidines. The infrared, ultraviolet, nuclear magnetic resonance and mass spectral properties of these materials were determined. (Author)
