Procedure

The procedure of Example 1 was followed using perfluoro-2-methyl-3-oxahexanoyl fluoride (16.6 g, 50 mmol), sodium trimethylsilanolate (5.6 g, 50 mmol), dry o-dichlorobenzene (200 mL), and 1 h at room temperature followed by rapid heating to 150°. Sodium perfluoro-2-methyl-3-oxahexanoate (13.6 g, 77% yield) was isolated as a white solid: The 19F NMR data were the same as reported in Example 15.
