The invention concerns a method for preparing alpha -halogenated ketones from secondary alpha -halogenated alcohols. More particularly, the invention concerns the preparation of alpha -trihalogenated ketones from secondary alpha -trihalogenated alcohols. The method for preparing said alpha -halogenated ketone is characterised in that it consists in oxidising in liquid phase, a secondary alpha -halogenated alcohol, using molecular oxygen or a gas containing same, in the presence of a catalyst based on a metal M1 selected among metals of group 1b and 8 of the periodic system of elements and optionally an activating element. |
