In a 50 ml glass reactor equipped with PTFE valve and magnetic stirring, 2.4 g (0.02 moles) of ClCF2—CH2—OH, 5 ml of tert-butyl alcohol, 1.1 g (0.02 moli) of KOH and 3.5 g of CF2═CFBr (0.022 moles) are fed. The reaction mixture is left under stirring at room temperature for three hours. The organic phase is then diluted with water, separated, washed twice with slightly acid water by HCl and anhydrified. 5 g of a mixture having the following composition: 89% ClCF2—CH2—O—CF2CFHBr and 11% CF2═CH—O—CF2CFHBr are obtained.
