A mixture of 15.03 g of 1-bromo-11-(nonafluorobutyl)undecane and 15.00 g of triethyl phosphite was heated at 150° C. After 18 hr, an additional 9.00 g of triethyl phosphite was added, and heating was continued for 24 hr. Diethyl ethylphosphonate and other volatiles were removed by distillation, b.p. 30-50° C. at 0.05 torr (7 Pa). Bulb-to-bulb distillation of the concentrate provided 16.07 g of 1-(diethylphosphono)-1-(nonafluorobutyl)undecane as a clear, colorless liquid, b.p. 170-200° C. at 0.05 torr (7 Pa).
