Abstract
By evaluating the obtained results of PM3 computations, the following correlations were found: (i) the diarylamines redox potentials (E) with the first ionization potentials (I); (ii) the pKa values characterizing both the amines nitrogen protonation and the carboxy substituted reagents dissociation via the COOH group, with the proton affinities of the corresponding diphenylamines and COO--containing anions; (iii) the experimental values of the molecules dipole moments (μ) with the theoretical ones. The feasibility of the simple semiempirical quantum chemical evaluation of E, pKa, and μ of the diphenylamine series as redox reagents was determined.Key words: diphenylamine series, redox potential, pKa, dipole moment, semiempirical quantum chemical evaluation
