2-phosphonopropanoic acid

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

Procedure: A solution of 2-phosphonopropionic acid (11.2 g., 0.073 moles) in methanol (150 ml.) is heated at reflux for eighteen hours. The methanol is removed in vacuo. Electrophoresis (0.1 N NH4HCO3, 2000 V, 20 minutes, 7.5 cm) indicates complete conversion to the desired product, methyl 2-phosphonopropionate; yield quantitative. at reflux for eighteen hours The methanol is removed in vacuo Electrophoresis (0.1 N NH4HCO3, 2000 V, 20 minutes, 7.5 cm) yield quantitative

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

Procedure: A mixture of ethyl-2-(diethoxyphosphinyl)propionate (15 g., 0.063 moles) in 6 N hydrochloric acid (150 ml.) is heated to reflux for 2.5 hours. After this time, the reaction vessel is fitted with a Dean-Stark trap and heated at reflux an additional thirty minutes. The reaction mixture is concentrated in vacuo to yield 2-phosphonopropionic acid (quantitative). is heated to reflux for 2.5 hours After this time, the reaction vessel is fitted with a Dean-Stark trap heated at reflux an additional thirty minutes The reaction mixture is concentrated in vacuo
