The present work focuses on the study of catalytic activity of polystyrene-supported p-toluenesulfonic acid (PS/PTSA) and the synthesis of alpha-aminophosphonates from the Kabachnik-Fields (KF) reaction under microwave irradiation in solvent-free conditions. Recently, the catalytic activity of PS/PTSA was tested with good yields. This procedure is the simplest, most straightforward, environment friendly method for the synthesis of alpha-aminophosphonates from simple to different substituted aldehyde substrates. Furthermore, this catalyst can be recovered and reused without loss of its catalytic activity.
