Pankratov, Alexei N. published the artcileSemiempirical quantum chemical PM3 computations and evaluations of redox potentials, basicities, and dipole moments of the diphenylamine series as analytical reagents, SDS of cas: 1821-27-8, the publication is Canadian Journal of Chemistry (1999), 77(12), 2053-2058, database is CAplus.
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 pKn values characterizing both the amines N 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 exptl. values of the mols. dipole moments (¦Ì) with the theor. ones. The feasibility of simple semiempirical quantum-chem. evaluation of E, pKa, and ¦Ì of the diphenylamine series as redox reagents was determined
