実験手順
A mixture of 3,5-dimethylhexa-1,5-dien-3-ol (0.126 g; 10-3 mol) and dichloro-bis-(benzonitrile)-palladium(II) (0.0153 g; 0.04.10-3 mol) in tetrahydrofuran (7.5 cc) is kept at a temperature of the order of 20° C. under an inert atmosphere. After a reaction time of 5 hours, diethyl ether (50 cc) is added and the reaction mixture is then washed with water (7×10 cc). After drying of the organic layer over magnesium sulphate and evaporation of the solvent under reduced pressure (20 mm Hg; 2.7 kPa), 6-methylhept-6-en-2-one (0.125 g) is obtained, which has the following characteristics:
