Procedure

FSO2CF2CF2OCF2CF2OCOCF(CF3)OCF2CF2CF3(3.1 g) obtained in Example 3 was charged into a flask together with NaF powder (0.02 g) and heated at 140° C. for 10 hours in an oil bath with vigorous stirring. At the upper portion of the flask, a reflux condenser having the temperature adjusted at 20° C., was installed. After cooling, the liquid sample (3.0 g) was recovered. As a result of the analysis by GC-MS, CF3CF(OCF2CF2CF3)COF and FSO2CF2CF2OCF2COF were confirmed to be the main products, and the NMR yield was 71.2%. Further, FCOCF(CF3)OCF2CF2CF3 was obtained in a yield of 74.0%.
