    Abstract: 1. A process for the preparation of cyclohexanedione derivatives of the general formula see diagramm : EP0124041,P7,F1 where R**1 means one of the following substituents : C2 -C8 -alkyl, C2 -C8 -alkenyl, C3 -C12 -cycloalkyl, C5 -C12 -cycloalkyl with 0-4 olefinically unsaturated bonds, C2 -C8 -alkylthioalkyl, C6 -C12 -bicycloalkyl with 0-3 olefinically unsaturated bonds, unsubstituted or substituted aryl or hetaryl, or a heterocyclic radical of 4 to 7 atoms of which not more than 3 may be hetero-atoms selected from the group consisting of O, S and N, the radical being saturated or olefinically unsaturated, by reaction of an alpha,beta-unsaturated ketone of the formula II see diagramm : EP0124041,P7,F2 with a dialkyl malonate in the presence of a base to give the alkoxycarbonylcyclohexenolone or its salt (III) see diagramm : EP0124041,P7,F3 and acylation, hydrolysis and decarboxylation of (III), R being the alcohol radical of the malonate and R**1 having the above meanings, wherein 1. the alpha,beta-unsaturated ketone (II) is reacted, in the presence of a base, with the dialkyl malonate in a solvent from which the alcohol liberated from the malonate can be distilled off, 2. the alcohol is distilled off, where appropriate as an azeotrope, 3. the salt of the alkoxycarbonylcyclohexenolone is reacted with a carboxylic acid halide R**2 COHal, where R**2 is alkyl of up to 6 carbon atoms, 4. the product, where appropriate after removal of excess acyl halide, is treated with an acylation catalyst, and 5. this product is hydrolyzed and decarboxylated.
