Title:
PROCESS FOR TRANSITION METAL FREE CATALYTIC AEROBIC OXIDATION OF ALCOHOLS UNDER MILD CONDITIONS USING STABLE FREE NITROXYL RADICALS
Document Type and Number:
Japanese Patent JP2006176527
Kind Code:
A
Abstract:
To provide a method for catalytically oxidizing an alcohol into the corresponding aldehyde and ketone under mild conditions in high selectivity at a high reaction rate and in a high yield, comprising using a combination of an environmentally friendly and easily handleable catalyst system with an oxygen-containing gas as a "clean" oxidant.
The alcohol can be oxidized by a process in which a primary or secondary alcohol is reacted with an oxygen-containing gas in the presence of a catalyst composition containing (i) a stable free nitroxyl radical derivative, (ii) a nitrate source, (iii) a bromide source, and (iiii) a carboxylic acid, thereby obtaining an aldehyde or a ketone.
