実験手順
To a solution of 11.54 g of 1-(diethylphosphono)-4-(nonafluorobutyl)butane in 50 mL of dichloromethane was added 10.7 g of bromotrimethylsilane. After 18 hr at room temperature, the solution was concentrated to a nearly colorless liquid, and the intermediate silylphosphonate ester was dissolved in 250 mL of methanol. The resultant solution was stirred at room temperature for 1 hr, and then concentrated to give a white solid. Dissolution in methanol and concentration were repeated two more times, and recrystallization of the crude product from acetonitrile gave 8.39 g of 1-phosphono-4-(nonafluorobutyl)butane (CF3(CF2)3(CH2)4PO3H2) as colorless needles, m.p. 123-124° C.
