A distinct approach for high-yielding synthesis of α-amino phosphonates has been discovered through three-component reaction of nitro compounds, aldehydes, or ketones and dialkyl or trialkylphosphites using indium in dilute aqueous HCl at room temperature. This one-pot conversion consists of the following steps: (i) reduction of nitro compounds to amines, (ii) formation of imines from amines and carbonyl
Abstract A supported acidic catalyst was easily prepared via anchoring imidazolium salt-based ionicliquid onto multiwalled carbon nanotube by covalent bonds. This novel immobilized acidic ionicliquid effectively catalyzed the one-pot synthesis of α-aminophosphonates from the reaction of amines and aldehydes with diethyl phosphite. The catalyst can be easily recovered and reused without appreciable

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

catalytic amount of tin(II) salts, the three-component Kabachnik-Fieldsreaction involving aldehydes, amines, and diethyl phosphite proceeded smoothly to afford the corresponding α-aminophosphonates in good to high yields. These reactions were carried out undersolvent-freeconditions. α-aminophosphonates - catalysis - imines - Lewis acids - solvent-free

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
