Fe3O4@SnO2/SO4-2 was prepared and applied as a heterogeneous nanocatalyst to synthesize α-amino phosphonate derivatives. The reaction was performed under solvent-free conditions at 80 °C. Synthesized compounds were characterized by FT-IR, ¹HNMR, and 13C-NMR. Magnetic properties lead to easy separation and reusability for several times. The simplicity of the procedure, easy workup, short reaction time, high efficiency, and toxic solvent removal are considerable advantages.
