Kasianchuk M. Regularities of oxidation of compounds with activated СН-bonds in polar media.

Kinetics of liquid phase heterolytic oxidation of anthrone with molecular oxygen and kinetics of oxidative cyclization of 4-(3,4-dimethoxyphenyl)-3-methyl-1-phenyl-5-(4-chlorobenzylidenamine)pyrazole had been studied. There is a strong influence of reaction medium - in first case rate influenting steps are base catalysed, in second - are carbon acid catalysed. In the case of anthrone aromatization carries out via the enol, that is ionized and oxidized after, but in the case of azometines the cyclization carries out via deprotonation by molecular oxygen. On the base of presented kinetic data, results of quantum computations and analysis of literature data a mechanism of anthrone oxidation has been proposed.
