1-[diethoxyphosphoryl(ethoxy)methoxy]ethane

Conditions: temp:135.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a flask containing triethyl orthoformate (23.6 gm; 0.16 mole) equipped with a magnetic stirrer, condensor, and nitrogen atmosphere, is added diethyl chloro phosphite (25 gm; 0.16 mole) over 15-30 minutes and an extremely exothermic reaction occurs. The reaction solution is then heated at 135° C. for 3 hours. The resulting solution is distilled using a Kugelrohr distillation apparatus at 80° C. (0.01 mm Hg) to yield 32 gm of diethoxymethylphosphonic acid diethyl ester (31P NMR 13.2 ppm). equipped with a magnetic stirrer an extremely exothermic reaction The resulting solution is distilled a Kugelrohr distillation apparatus at 80° C. (0.01 mm Hg)
