Abstract:
In recent years, there has been increasing emphasis on the design and application of environmental friendly catalysts to reduce the quantity of toxic wastes. In this project , BaFe12O19/Al2O3 magnetic nanocomposites were designed, synthesized and identified and used as a catalyst for the synthesis of a-aminophosphonates. The application of this catalyst is investigated through three-component reactions aldehydes/ ketones, amines and nucleophile such as triethyl phosphite. Using magnetic heterogeneous catalyst in these reaction result easy work up, high product yield and short reaction time in solvent free conditions.
