Versuchsvorschrift
A mixture of 18.04 g of 1-bromo-6-(nonafluorobutyl)hexane and 19.6 g of triethyl phosphite was heated at 150° C. After 18 hr, an additional 10.0 g of triethyl phosphite was added, and heating was continued for 8 hr more. Diethyl ethylphosphonate and other volatiles were removed by distillation, b.p. 30-50° C. at 0.05 torr (7 Pa), and bulb-to-bulb distillation of the concentrate provided 18.88 g of 1-(diethylphosphono)-6-(nonafluorobutyl)hexane as a clear, colorless liquid, b.p. 120-130° C. at 0.05 torr (7 Pa).
