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

A green novel synthesis of ZnO@CuO@Iron ore nanocomposites as a novel and magneticheterogeneousnanocatalyst is used for the one-pot synthesis of α-aminophosphonates under solventless conditions. This study benefits from the magneticiron ore acting as a multi-mineral Lewis acid system, the green properties and the large surface area due to its nanostructure. Moreover, scanning electron microscope

A simple and efficient method has been developed for the synthesis of α-aminophosphonates by a one-pot three-component condensation of aldehydes, amines and diethyl phosphite in the presence of a catalytic amount of silicasulfuricacidunder solvent-free reaction conditions. The major advantages of the present method are good yields, inexpensive, ecofriendly and reusable catalyst, short reaction times

A convenientsynthesis of different types of α-aminophosphonates via one-pot solvent-free three component reactions of aldehydes, amines and phosphites catalyzed by bismuth salts has been investigated. Bismuth triflate is found to be the most effective catalyst for this reaction.
Zinc oxide nanoparticles (ZnO NPs, ca. 22 nm) were used as an effective catalyst in the solvent-free, three-component couplings of aldehydes, aromatic amines and dialkyl phosphites at room temperature to produce various α-amino phosphonates. Compared to known methods, satisfactory results were obtained with high yields through a simple experimental procedure. The catalyst was recycled and reused five times with minor decrease in its catalytic activity.
