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

An atom-efficient, one-pot, three-component synthetic methodology has been developed for the preparation of α-aminophosphonates using the crystalline CuO- nanopowder as catalyst in solvent-free and ambient conditions, for the first time. The reaction involves the use of carbonyl compounds, amines and trimethyl phosphite. A wide range of substrates is compatible in this reaction, producing excellent
