1 EXAMPLE 1
EXAMPLE 1 Triethyl Phosphonopropionate: Ethyl bromopropionate (92 g 0.5 mole) and triethyl phosphite (83 g, 0.5 mole) were stirred and heated to about 200° C. under a air cooled reflux condenser. The ethyl bromide that was evolved was collected with the aid of a cooling trap. After 1 hour of heating the pot temperature went up to 230° C. At this point the evolution of ethyl bromide ceased. The yellow oil was cooled to room temperature (RT) and then distilled under vacuum. There was obtained 112 g of phosphonate (93%) boiling at 105° /20 mm Hg as a colorless oil.
