    • Typical Procedure A solution of benzaldehyde (0.107 g, 1 mmol, trimethylphosphite (0.136 g, 1.1 mmol, and Amberlyst-15 (0.1 g) in H 2O (2 mL) was placed in a round-bottomed flask equipped with a magnetic stirrer and was heated at 50°C The stirring was continued for 1.5 h. After completion of the reaction as indicated by TLC, the reaction mixture was treated with aq sat. NaHCO3 solution followed by brine and the product was extracted three times with 5 mL CH2Cl2, dried over anhyd MgSO4, and concentrated to give an oily residue, which was crystallized to give 0.216 g (95, of dimethyl 1-hydroxy-1- phenylmethylphosphonate.
