Document Type and Number:
Japanese Patent JP4727806
Kind Code:
B2
Abstract:
Selective oxidation of alcohols to ketones with an alkali hypohalide comprises using an insoluble heterogeneous oxidation catalyst or a 4-oxy-2,2,6,6-tetramethylpiperidin-1-oxyl 4-oxy-bound to a Merrifield polymer. Selective oxidation of alcohols to ketones with an alkali hypohalide under alkaline conditions comprises using an insoluble heterogeneous oxidation catalyst of formulas (I), (II) or (III) or a 4-oxy-2,2,6,6-tetramethylpiperidin-1-oxyl 4-oxy-bound to a Merrifield polymer; n = 3-3000. An Independent claim is included for the compounds per se.
