A mixture of 21.69 g (60 mmol) of 1-bromo-3,7,11,15-tetramethylhexadecane and 25 g (150 mmol) of triethyl phosphite was heated at 150° C. After 18 h, an additional 20 g (120 mmol) of triethyl phosphite was added, and heating was continued for 24 h. Diethyl ethylphosphonate and other volatiles were distilled, bp 30-50° C. at 0.05 mm Hg, and bulb-to-bulb distillation of the concentrate provided 23.51 g (94%) of 1-(diethylphosphono)-3,7,11,15-tetramethylhexadecane as a clear, colorless liquid, bp 190-230° C. at 0.05 mm Hg.
