Direct catalytic oxidation of lower alkanes in ionic liquid media

Chepaikin, E. G. / Bezruchko, A. P. / Menchikova, G. N. / Moiseeva, N. I. / Gekhman, A. E.

Abstract Immobilization of rhodium (palladium)-copper-chloride catalytic systems in ionic liquids as high-boiling-point solvents affects the distribution of propane oxidation products: the acetone yield increases and the yield of alcohols decreases. Propane is oxidized to acetone, bypassing the isopropanol formation step. Methane is oxidized under more severe conditions than propane, giving methyl trifluoroacetate as the main product. Mechanisms of action of the catalytic systems based on rhodium and palladium are close to each other and likely include oxo or peroxo complexes as intermediates.
