Reaction Conditions

Reaction Steps

A solution of sodium dipentyl phosphite was prepared by adding 80 g (0.36 mol) di n-pentyl phosphite to a suspension of 8.6 g (0.29 mol) 80% sodium hydride in 150 ml tetrahydrofuran followed by heating the mixture at 60° until total consumption of sodium hydride. To this solution were added 40 g (0.08 mol) ditosylate of 2-(3-phenylpropyl)-1,3-propanediol dissolved in 150 ml dioxane and the resulting mixture was heated at 80° C. overnight. After work up of the reaction, ball-tube distillation afforded 38 g (79%) of tetrapentyl 2-(3-phenylpropyl)-1,3-propylidenediphosphonate.
