Chernyshevsky State University, ul. Astrakhanskaya 83, 410012, Saratov, Russia aut Quantitative structure-property relationships in the series of diazonium cations, intermediate products in the synthesis of analytical forms and dyes [Elektronische Daten] [A. Pankratov] It was demonstrated that the reduction potentials, dimerization potentials, and half-equivalence point potentials in the titration of aryldiazonium cations XC6H4N+≡N are linearly related to the quantum-chemically calculated values of electron affinities (A) and stabilization energies of radicals formed in the reduction of diazonium cations. Linear correlations between the frequencies (v) characterizing the set of stretching vibrations in the C—N+≡N fragment of XC6H4N+≡N cations and N≡N and C—N bond orders, charges on carbon atoms in the para positions of aromatic rings of C6H5X molecules, and mesomeric dipole moments (µm) of substituents X were found. Quantitative relationships relating µm and v to A were revealed. These relationships have clear physical meaning, are characterized by relatively large correlation coefficients, and possess predictive power for redox properties, electron affinity, and vibrational spectra of aryldiazonium cations and mesomeric dipole moments of atomic groups in organic molecules.
