実験手順
Hexafluoropropylene oxide (HFPO, 300 g) was added to 50 g of 25% sodium methoxide in methanol plus 450 g methanol at room temperature in a modification of the procedure of (J. Org. Chem. 31, 2312 (1960) to give CH3OCF(CF3)COOMe bp 110-118° C. This was direct fluorinated according to U.S. Pat. No. 5,488,142 and the product was methanolysed to give the same ester as in Example 11. One could then convert this to the perfluorovinyl ether as described above.
