Abstract An efficient method has been developed for the preparation of α-aminophosphonates by using zinc di(l-prolinate) as a catalyst under mild reaction conditions. The method has the advantages of high yields, short reaction times, and easy workup conditions. An efficient method has been developed for the preparation of α-aminophosphonates by using zinc di(l-prolinate) as a catalyst under mild reaction

Herein we introduce a new catalyst for the Kabachnik–Fields reaction, [Ce(L-Pro)]2(Oxa), using a very accessible, simple and efficient methodology for α-aminophosphonate synthesis using an aromatic aldehyde, an aromaticamine and diphenyl phosphite. This procedure was developed using a low catalyst loading of cerium(III) prolinate and it has allowed for the recycling of the catalyst.

Zirconium(IV) compounds are reported as excellent catalysts for a three-component one-pot reaction of an amine, an aldehyde or a ketone, and a di/trialkyl/aryl phosphite to form α-aminophosphonates under solvent-free conditions at rt. Among the various zirconiumcompounds, ZrOCl2·8H2O and ZrO(ClO4)2·6H2O were most effective. The reactions were faster with dialkyl/diaryl phosphites than with trialkyl/triaryl

an extremely efficient catalyst for the synthesis of α-aminophosphonates. A three-component reaction (3-CR) of an amine, an aldehyde or a ketone, and a di-/trialkyl phosphite (Kabachnik−Fields reaction) took place in one pot under solvent-free conditions to afford the corresponding α-aminophosphonates in high yields and short times. The use of solvent retards the rate of the reaction and requires a
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
