実験手順
63.6 g (1 mol) of powdered technical grade potassium hydroxide (88% strength) are suspended in 200 ml of toluene, and 10 g of trioctylammonium chloride are added. A mixture of 76.5 g (1 mol) of allyl chloride and 129 g (1.5 mols) of methyl isopropyl ketone is then added dropwise so that the temperature does not exceed 70° C. The mixture is stirred for a further 4 hours at 70° C., and is worked up as in Example 1. 96 g (76% of theory) of 4,4-dimethylhex-1-en-5-one of the abovementioned boiling point are obtained.
