(4-hydroxybenzylideneamino) (phenyl) methyl phosphonate) (DHBMP), and (E)-diethyl (4-nitrobenzylideneamino)(phenyl)methylphosphonate (DNPMP) with high yields form the condensation reaction of diethyl (α-aminobenzyl)phosphonate hydrochloride and the corresponding substituted benzaldehyde. The synthesized compounds were analyzed by various spectroscopic techniques such as NMR, MS, UV–Vis, and IR spectroscopy

synthetic accessibility of amides render them valuable precursors for the synthesis of diverse nitrogen-containing compounds. Herein, we present a metal-free and streamlined synthetic strategy for the synthesis of quaternary α-aminophosphonates. This approach involves sequential deoxygenative nucleophilic phosphonation and versatile electrophilic alkylation of secondaryamides in a one-pot fashion. Notably
