摘要: Abstract Diarrylamines ArNHAr′ (Ar = 2,4,6-tri-, 2,6-di- or 2,4-dinitrophenyl, and Ar′ phenyl a with electron-donating substituents) were prepared; their IR UV spectra, electrooxidation electroreduction potentials studied. Oxidation of picryl- 2,6-dinitrophenyl-substituted compounds Ag2O affords paramagnetic solution giving ESR signals has MeO NR2 substituents. Radicals IVi Vi are stable even in crystalline state.
