HCID 22902895Sec.Butyl Bis(beta-Carboxyethyl)Phosphine Oxide

Versuchsvorschrift

Sec. butylphosphine, 592 parts (85% purity) is reacted with 860 parts of methyl acrylate containing 4.9 parts of azobis(isovaleronitrile) at 67°-100° C. for 3.5 hours. The reaction product, sec. butylbis(carbomethoxyethyl)phosphine is reacted with 10% molar excess hydrogen peroxide (25% solution) for two hours at 60° C. to give the corresponding phosphine oxide. The latter is hydrolyzed with dilute sulfuric acid to give after recrystallization from water, sec. butyl bis(β-carboxyethyl)phosphine oxide.
