Patent ID: 7015358

Claim:
A process for the production of an aliphatic or alicyclic monoketone or an alicyclic diketone of the formula: R 1 —C(═O)—R 2 (I) in which R 1 is a linear or branched C 1-10 -alkyl, and R 2 is a linear or branched C 1-10 -alkyl or a phenyl, or R 1 or R 2 together are —(CH 2 ) m —[C(═O)] n —(CH 2 ) 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 (I), by oxidizing a secondary alcohol of formula R 1′ —CHOH—R 2′ (II) in which R 1′ and R 2′ either have the same meaning as R 1 and R 2 above or, if R 1 and R 2 together are —(CH 2 ) m —[C(═O)] n —(CH 2 ) p —, are together —(CH 2 ) m —(CHOH) n —(CH 2 ) 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.
