| titleOfInvention | Process for the preparation of 2-alkyl-cyclopentanones |
| abstract | 1. A process for the preparation of a cyclopentanone which is monoalkylated in the 2-position and of the formula I see diagramm : EP0194591,P6,F2 where R**1 is a branched or straight-chain aliphatic group of 2 to 12, preferably 4 to 8, carbon atoms and R**2 to R**7 may be identical or different and are each hydrogen or alkyl of 1 to 5 carbon atoms, preferably hydrogen or methyl, wherein a cyclopentanone of the formula II see diagramm : EP0194591,P6,F3 or a corresponding cyclopentanone, is reacted with an aldehyde of the formula III see diagramm : EP0194591,P6,F5 where R**1 has the above meanings, at from 80 to 280 degrees C, preferably from 100 to 200 degrees C, in the presence of hydrogen in an autoclave, over a catalyst which contains, as active components, on the one hand an oxide or a phosphate of magnesium, aluminium, titanium or zinc or of a rare earth metal, and on the other hand a noble metal of group VIII of the periodic table, preferably palladium. |
