Versuchsvorschrift

To 2-bromododecanoic acid (1 g), after having been dissolved in acetonitrile (50 ml ), were added calcium chloride (2 g) and tetraethylammonium chloride (1 g), and the mixture was heated under reflux for 4 hours. The reaction mixture was filtered, concentrated and distributed into ethyl acetate and water, and the ethyl acetate layer was dried over anhydrous sodium sulfate and concentrated to give 2-chlorododecanoic acid.
