Nano Fe3O4 as magnetically recyclable catalyst for the synthesis of α-aminophosphonates in solvent-free conditions

The three component, one-pot synthesis of alpha-aminophosphonates has been achieved using super magnetic nano iron oxide at 50 degrees C under solvent-free conditions in excellent yields. The major advantages of the present method are high yields, short reaction times, magnetically recyclable catalyst, and solvent-free reaction conditions. (C) 2011 Elsevier Ltd. All rights reserved.
