Aqueous sodiumperoxide oxidises the conjugated Δ4-3-ketosteroids - to the corresponding Δ4-3-4-diones in good yield. Saturated carbonyl and alcohol groups are not affected by the reaction.
Catalytic N2O oxidation of various secondary and benzylic alcohols using a ruthenium porphyrin complex is presented. Both secondary and benzylic alcohols were smoothly consumed to give the corresponding ketones and aldehydes in high yields. Nitrous oxide (N2O) is expected to be a new terminal oxidant producing only dinitrogen gas as the only by-product to provide a less wasteful process.
