Conditions

Temperature: 150 °C

Procedure

A mixture of 0.98 g of 1-bromo-22-(nonafluorobutyl)docosane and 4.00 g of triethyl phosphite was heated at 150° C. After 18 hr, diethyl ethylphosphonate and other volatiles were distilled, b.p. 30-50° C. at 0.05 torr (7 Pa), leaving 1.09 g of 1-(diethylphosphono)-22-(nonafluorobutyl)docosane as an off-white solid, which was used without further purification.

Workup

distillationdiethyl ethylphosphonate and other volatiles were distilled
