Procedure

5.16 g (20 mmols) of 1-chloro-3,3-dimethyl-2-(p-chlorophenoxy)-1,4-pentadiene, prepared according to Example A2(a) above, are warmed to 50° C. in a mixture of 20 ml of formic acid and 2 ml of concentrated hydrochloric acid, during the course of 2 hours. The working-up corresponding to Example B1(a) yields 2.47 g of 1-chloro-3,3-dimethyl-pent-4-en-2-one, which are 84% of theory.
