Procedure

Diphenyl ethoxycarbonylphosphonate (3.06 g) and sodium hydrogencarbonate (0.84 g) were stirred in water (10 ml) at room temperature for about 24 hours. The solvent was evaporated and the residue extracted with ethanol. The ethanol was evaporated and the residue was washed with ether. The residue was recrystallized twice from isopropanol. Colourless crystals (0.67 g, 27%) were obtained. Thin layer chromatography on silica gel, eluted with ethanol and developed with iodine vapor: Rf 0.66. By t.l.c. the compound was estimated to contain <0.4% of trisodium oxycarbonylphosphonate.
