Versuchsvorschrift

20 g (0.0926 mol) of 2,2-dimethyl-6-phenoxy-hex-4-in-3-one are dissolved in 180 ml of methanol, and 5 g of Raney nickel are added. The mixture is hydrogenated with hydrogen under a pressure of 50 to 60 bar at 37° C. The hydrogenation has ended after 40 minutes. The reaction mixture is filtered and the filtrate is concentrated by stripping off the solvent under reduced pressure. 19.5 g (95.7% of theory) of 2,2-dimethyl-6-phenoxy-hexan-3-one are obtained in this manner.
