Reaktionsschritte
1,2,3,4-Tetrafluorobenzene (67.7 g), sodium hydrobromide (20.8 g), and 200 ml of ethyleneglycol are refluxed with good stirring for 3 hours. The reaction mixture is poured into water (800 ml), acidified with 10% hydrochloric acid and then extracted with ether. The ether is washed with dilute sodium hydroxide and water, and then distilled under vacuum to give 2-(2,3,6-trifluorophenoxy) ethanol), b.p. about 100° at 15 min.
