Abstract: The acetyl and benzoyl o-nitroanilines 1a and 1b and the acetyl and benzoyl o-nitrodiphenylamines 1c and 1d have been reduced chemically (Bu(t)OK/DMSO) and electrochemically inside the cavity of an EPR spectrometer. For all compounds the EPR signal of the radical anions could be recorded and interpreted. In DMSO the radical anions 1c.- and 1d.- evolved to the phenazine radical anion within 1 h. The polarographic study showed that the four compounds are reduced in two different steps, the first being monoelectronic and reversible, as demonstrated by cyclic voltammetric experiments.
