, p. 683 - 688 (2016)
A supported acidic catalyst was easily prepared via anchoring imidazolium salt-based ionic liquid onto multiwalled carbon nanotube by covalent bonds. This novel immobilized acidic ionic liquid 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 change in its efficiency.

A direct approach to important α-amino phosphonic acids and its derivatives has been developed by using copper-catalyzed electrophilic amination of α-phosphonate zincates with O-acyl hydroxylamines. This amination provides the first example of C=N bond formation which directly introduces acyclic and cyclic amines to the α-position of phosphonates in one step. The reaction is readily promoted at room temperature with as little as 0.5 mol % of catalyst, and demonstrates high efficiency on a broad substrate scope. A direct approach to important α-amino phosphonic acids and derivatives, by using copper-catalyzed electrophilic amination of α-phosphonate zincates using O-acylhydroxylamines, is described. This amination is the first example of C=N bond formation which directly introduces acyclic and cyclic amines to the α-position of phosphonates in one step. The reaction proceeds at room temperature with as little as 0.5 mol % of the catalyst. Copyright
Synthesis of α-aminophosphonates using polystyrene supported Al(OTf)3 as a heterogeneous catalyst
Boroujeni, Kaveh Parvanak
experimental part, p. 173 - 176 (2011/04/25)
A mild and efficient method has been devised for the preparation of -aminophosphonates from three component condensation of an aldehyde, an amine, and diethyl phosphite in the presence of catalytic amounts of cross-linked polystyrene supported aluminium triflate (Ps-Al(OTf)3) under solvent-free conditions in good to excellent yields. The catalyst is stable (as a bench top catalyst) and can be easily recovered and reused without appreciable change in its efficiency. Taylor & Francis Group, LLC.
Silica gel and polystyrene supported aluminum chloride as heterogeneous catalysts for the preparation of α-aminophosphonates
Boroujeni, Kaveh Parvanak,Shirazi, Amir Nasrolahi
experimental part, p. 418 - 422 (2011/06/28)
Silica gel supported aluminum chloride (SiO2-AlCl3) and cross-linked polystyrene-supported aluminum chloride (PS-AlCl3) are environment- friendly heterogeneous catalysts 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 their efficiency.
