Abstract
The present invention relates to a process of oxidation of alcohols selectively to aldehydes or ketones with NaOCl using a TEMPO—borate catalyst system. It is shown that the oxidation can be efficiently carried out without KBr additives under solvent free conditions. Aldehydes such as 3,3-dimethylbutyraldehyde can be produced efficiently using the present invention.
