Procedure

4.44 g (20 mmols) of 1-chloro-3,3-dimethyl-2-phenoxy-1,4-pentadiene are warmed to 100° C. in 20 ml of dioxane and 10 ml of 50% sulphuric acid, during the course of 6 hours. The working-up according to Example B1(a) yields 2.1 g of 1-chloro-3,3-dimethyl-pent-4-en-2-one, which are 72% of theory.
