Magnetic mesoporous poly‐melamine–formaldehyde: an e cient and recyclable catalyst for straightforward one‐pot synthesis of α-Aminophosphonates

Magnetically separable mesoporous poly-melamine–formaldehyde nanocomposite (PMF@Fe3O4-SO3H) has been synthesized and characterized by FTIR spectroscopy, SEM, XRD spectroscopy and EDS. The magnetically separable PMF@Fe3O4-SO3H catalyst had excellent e ciency for the synthesis a wide diversity of α-Aminophosphonates by a three-component reaction of a Amines, aldehyde and Trimethyl Phosphite in good-to-excellent yields within a short reaction time, through an environmental friendliness and straightforward procedure. The nanocomposite that is easily recoverable and also found to be reusable can be recovered and reused when the reaction is completed for several times without distinct deterioration in catalytic activity.
