Versuchsvorschrift

580 g (1.5 mols) of 1-chloro-3,3-dimethyl-1,5-di-(4-chlorophenoxy)-1-pentene in 1,000 ml of ethanol and 300 ml of concentrated hydrochloric acid are heated under reflux for 4 hours. The ethanol is removed in vacuo, and the residue is diluted with methylene chloride and extracted by shaking with water, and then three times with dilute sodium hydroxide solution. The dried solution is freed of solvent in vacuo. 363 g (88% of theory) of 1-chloro-5-(4-chlorophenoxy)-3,3-dimethyl-2-pentanone are obtained as an oil.
