Quantum-Chemical Study of Reaction Laws of 2,4,6-Triphenylpyranyl Radical with Oxygen

Abstract

Reaction of stable electron-excessive radicals with oxygen is aided by preliminary one-electron transfer between them. The rearrangements of the formed oxide radicals are governed by their nature and by electronic characteristics of the reacting atoms. In the reactions occurring in a “cage” of the solvent molecules the energy of exothermic stages may accumulate for the initiation of the conjugated endothermic stages. The discovered laws can be used in the interpretation of the features of the chemical properties of stable organic radicals.
