PROCESS FOR THE SELECTIVE OXIDATION OF ALCOHOLS USING READILY REMOVABLE NITROXYL RADICALS

摘要

The invention relates to a process for the selective oxidation of alcohols t o 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 t he compounds of formula (I) (see formula I, see formula II, see formula III) 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 t o the use of the above-mentioned oxidation catalysts for the oxidation of alcohols.
