Magnetic ZnO@CuO@Iron ore Nanocomposites as a Green and Highly Efficient Heterogeneous Nanocatalyst for Solventless Synthesis of α-aminophosphonates

A green novel synthesis of ZnO@CuO@Iron ore nanocomposites as a novel and magnetic heterogeneous nanocatalyst is used for the one-pot synthesis of α-aminophosphonates under solventless conditions. This study benefits from the magnetic iron ore acting as a multi-mineral Lewis acid system, the green properties and the large surface area due to its nanostructure. Moreover, scanning electron microscope analysis confirmed that the nanocatalyst gave an excellent yield and good recyclability; which, even after the 10th cycle of the model reaction retained its potential with no significant loss of catalytic activity.
