Reaction Steps

30.8 g potassium hydroxide was dissolved in 400 ml of water, 100 g (0.4715 moles) of 2,2,3,3,4,4-hexafluoropentane-1,5-diol (prepared essentially as described supra) was added, and the resulting mixture was heated to 90° C. Over a period of one hour, 74.9 g (0.480 moles) of ethyl iodide was added to the flask via an addition funnel with rapid stirring. The reaction flask was then heated to reflux for two hours. The reaction mixture was cooled to room temperature, and the bottom product phase (87.1 g) was split away from the aqueous layer. The crude product was distilled at 6.0 mm Hg (6.0 torr) to give 58.8 g of 2,2,3,3,4,4-hexafluoro-5-ethoxypentanol distilling at 85°-91° C. (conversion=68%; yield based on converted material=76%).
