The present invention discloses a method for preparing aldehydes or ketones via aerobic oxidation of alcohols with the copper salts and nitroxide radicals as catalysts. Both oxygen and air could be used as oxidants, after 4 to 48 hours of reaction in an organic solvent at room temperature, the alcohols are efficiently oxidized to the corresponding aldehydes or ketones. The present invention has the following advantages: easy to operate, refraining from using chlorides which are corrosive to equipment, readily available raw materials and reagents, mils reaction conditions, the broad substrate scope, good functional group tolerance, convenient purification, environmentally friendly and no pollution. Thus, the method is suitable for industrial production.

The invention relates to a process for preparing an α-methylene ketone comprising the step of reacting a ketone with formaldehyde in the presence of a catalyst which is an organic compound comprising at least one acid function or the corresponding salt, ester or amide thereof and at least one amine function or the corresponding ammonium salt, or a zwitterion thereof.
