Heating trialkyl phosphites with N-acyl aziridines produces dialkyl 2-amidoethyl-phosphonates bearing one of the phosphite alkyl groups on nitrogen. Other alkoxy phosphines behave analogously. Dialkyl phosphites furnish the same type of products devoid of the N-alkyl group.

Aminoalkylphosphonic acids are prepared via amino group protection by nitrogen-phosphorus (P-N) bond formation. Phosphorylation of β or γ-bromoalkylamines with chlorophosphates followed by reaction of the resulting haloalkylphosphoramidates with triethylphosphite (Arbuzov reaction) to give a phosphoramidate-phos-phonate intermediate which can be alkylated with various reagents. Removal of the phosphoryl
