The invention concerns a method for preparing &agr;-halogenated ketones from secondary &agr;-halogenated alcohols. More particularly, the invention concerns the preparation of &agr;-trihalogenated ketones from secondary &agr;-trihalogenated alcohols. The method for preparing said &agr;-halogenated ketone is characterized in that it consists in oxidizing in liquid phase, a secondary &agr;-halogenated alcohol, using molecular oxygen or a gas containing same, in the presence of a catalyst based on a metal M
