Abstract
Abstract Non-traditional mechanisms are considered for catalytic oxidation of hydrocarbons with emphasis on alkanes oxidation, including methane: ( i ) Activation of alkanes by metal complexes in solution via metal-alkyl intermediates with their subsequent oxidation. ( ii ) Chemical models of biological oxidation: coupled oxidation of a hydrocarbon molecule and an electron donor which involves reduction of a metal complex, its oxidation by dioxygen to high-valent compound and subsequent reaction of the latter with the hydrocarbon molecule. ( iii ) Coupled oxidation of a hydrocarbon and non-metallic compound. Besides well-known radical-chain mechanism another mechanism can operate in polar media involving radical ions. The latter can be sufficiently active to react with hydrocarbons including alkanes.
