Add 0.1 mol of phenylphosphonium dichloride to the constant pressure dropping funnel with stirring, use the ice water bath and adjust the dropping speed of phenylphosphine dichloride, The reaction temperature was controlled at about 0C, and after completion of the dropwise addition, the mixture was stirred at about 45C for 2.5 hours. After the reaction is completed, the reaction solution is poured into a beaker, cooled and filtered to obtain a solid crude product of diethyl phenylphosphonate. The product was recrystallized from a mixture of petroleum ether and dichloromethane to obtain a pure product with a yield of 87.5%.

The mixture was heated at reflux for 1/2 hr., then 100 mL of 25% sulfuric acid was added cautiously. Three layers formed; the bottom (aqueous) layer was extracted with toluene. Addition of NaHCO3 to the combined upper layers produced a vigorous reaction and a single organic phase. The organic phase was washed with water and with saturated NaCl, dried and evaporated to give an oil (14 g). Kugelrohr distillation at 120°-160° C. (0.1 mmHg) followed by chromatography on silica gel (CHCl3), then 10% MeOH--CHCl3) gave 7.1 g of an oil. This was distilled in the Kugelrohr again (150° C., 0.1 mmHg) to give 6.2 g of product which appears to be pure by NMR and crystallized on standing. 1 H NMR (CDCl3) δ8.0-7.2 (m, 9H), 8.08 (d, J=480 Hz, 1H), 2.42 (s, 3H).

The excess phosphonite was removed by passing the reaction mixture down a wiped wall still at 80° C. at a pressure of 0.013 mb. The residue was distilled on a wiped wall still at a temperature of 110° C. and a pressure of 0.013 mb and the product, ethyl(2-oxo-4-oxetanylmethyl)phenylphosphinate, was obtained as a colourless oil which was shown by 31 P NMR to be a nearly equal mixture of diastereoisomers having chemical shifts at δ-37.5 and δ-37.7 and which had the following elemental analysis by weight.
