for the one-pot synthesis of diethyl α-aminophosphonates from aldehydes, amines and diethylphosphite (Kabacknik-Fields reaction) in SDS micellar solution in aqueous media is described. The synthesis of α-aminophosphonates in the present study represents a three-component reaction in which no intermediate formation of either an imine or α-hydroxyphosphonate was observed. aldehydes - amines - α-aminophosphonates
Silica gel supported aluminum chloride (SiO2-AlCl3) and cross-linked polystyrene-supported aluminum chloride (PS-AlCl3) are environment- friendly heterogeneouscatalysts for the condensation of amines and aldehydes with diethyl phosphite to afford α-aminophosphonates. These solid acid catalysts are stable (as bench top catalysts) and can be easily recovered and reused without appreciable change in

extremely well for the synthesis of α‐aminophosphonates even up to five subsequent trails without significant loss of its catalytic activity or copper leaching. The TEM image and FT‐IR spectrum of the catalyst after five times recovery showed that the structure of the catalyst was stable under the reaction conditions with no change being observed. The strong magnetic properties of the reused catalyst were
A new, convenient and high yielding procedure for the preparation of diethyl α-aminophosphonates in water by one-pot reaction of aldehydes, amines, tri/dialkyl phosphites in the presence of a low catalytic amount of [Cu(3,4-tmtppa)](MeSO4)4 (0.16 mol%) as a highly stable and re-usable catalyst is described.
Iron-doped single walled carbon nanotubes as an efficient and reusable heterogeneous catalyst for the synthesis of organophosphorus compounds under solvent-free conditions
Iron-doped single walled carbon nanotubes (Fe/SWCNTs) is an efficient, eco-friendly, and reusableheterogeneouscatalyst for the synthesis of diversely decorated α-aminophosphonates via multicomponent reaction of amines, carbonyl compounds, and phosphorus compounds undersolvent-freeconditions. This methodology illustrates a very simple procedure, with wide applicability, extending the scope to aliphatic
