Reaction Steps

Perfluoroheptanoic acid 9.5 g (0.026 mole), iodine 4.0 g (0.016 mole) and Freon 113 (500 ml) were mixed and treated with approximately 33% fluorine diluted with nitrogen until the color due to iodine disappeared. The mixture was washed with water containing a small amount of sodium thiosulfite and dried over magnesium sulfate. 1.5 g (13% yield) of perfluorohexyl iodide was obtained.
