## Abstract __N__,__N__′‐Alkylidenebisamides 1, totally unsuitable as amidoalkylating agents toward phosphorous acid, react with its “activated” form prepared “in situ” from phosphorus(III) chloride and acetic acid to give the desired 1‐aminoalkylphosphonic acids 2 in high yields.

A convenient 31P NMR method for determining the enantiomeric excess of free 1-aminoalkylphosphonic acids is presented. It was found by NMR that the interaction of Pd" ions with 1-aminophosphonate ligands (L) yields, in a non-diastereoselective manner, diastereoisomeric chelate pairs (PdL,) observabl
