ABSTRACT:
A process for the production of aliphatic or alicyclic monoketones or alicyclic diketones of the formula R1—C(═O)—R2in which R1is a linear or branched C1-10-alkyl group and R2is a linear or branched C1-10-alkyl group or a phenyl group, or R1or R2together are —(CH2)m—[C(═O)]n—(CH2)p—, wherein m and p independently are integers from 1 to 4 and n is 0 or 1, thus forming an alicyclic ring together with the carbonyl group of R1—C(═O)—R2by oxidizing a secondary alcohol of formula R1′—CHOH—R2′in which R1′and R2′either have the same meaning as R1and R2above or, if R1and R2together are —(CH2)m—[C(═O)]n—(CH2)p—, are together —(CH2)m—(CHOH)n—(CH2)p— wherein m, n and p are as defined above, with a peroxy compound in the presence of a carboxylic acid and a manganese(IV) complex of 1,4,7-trimethyl-1,4,7-triazacyclononane.
