Abstract
The invention relates to a process for the selective oxidation of alcohols to ketones or to aldehydes by means of an alkali hypohalite under alkaline conditions, which comprises carrying out the oxidation in the presence of a heterogeneous oxidation catalyst that is insoluble in the reaction medium and is selected from the group comprising the compounds of formula (I) wherein n is a number from 3 to 3000; or a 4-oxy-2,2,6,6-tetramethylpiperidin-1-oxyl that is 4-oxy-bound to a Merrifield polymer. The invention relates also to the compounds of formulae (II) and (III) and to the use of the above-mentioned oxidation catalysts for the oxidation of alcohols.
