Abstract It has been found that cobalt(III) trifluoroacetate is capable of oxidizing with a high selectivity (∼90%) methane to methyltrifluoroacetate at 130–180°C and 10–40 atm. In the presence of oxygen the selective oxidation of methane proceeds catalytically with respect to the cobalt salt. Ethane and propane are oxidized with the formation of ethanol and isopropanol trifluoroacetates, respectively (yield ∼80%). The further oxidation of triethanol trifluoroacetate leads to the formation of the ethyleneglycol ester, together with products of the splitting of the C-C bond in the alkyl group of the initial ester. The data obtained lead to the assumption that the reactions of the alkanes and alkyl esters with Co(III) include an electron transfer stage from the RH molecule to the Co(III) ion, with the intermediate formation of the cation radical RH⋅+.
