PROCESS FOR THE PREPARATION OF 3,5,5-TRIMETHYL-CYCLOHEX-2-ENE-1,4-DIONE

摘要

The present invention relates to an improved process for the preparation of 3,5,5-trimethylcyclohex-2-ene-1,4-dione by oxidation of 3,5,5-trimethylcyclohex-3-en-1-one in the presence of an oxidizing agent and a catalyst system comprising a transition metal complex catalyst, an auxiliary base, possibly water, and a catalytically active co-additive, characterized in that carboxylic acid amides are employed as the solvent.
