Synthesis of 1-Aminoalkylphosphonic Acids via Amidoalkylation of Phosphorous Acid by N,N'-Alkylidenbisamides
N,N'-Alkylidenebisamides 1, totally unsuitable as amidoalkylating agents toward phosphorous acid, react with its "activated" form prepared "in situ" from phosphorous(III) chloride and acetic acid to give the desired 1-amidoalkylphosphonic acids 2 in high yield.
