Silica supported polyphosphoric acid (PPA-SiO2): an efficient and reusable heterogeneous catalyst for the one-pot synthesis of a -amino phosphonates

An efficient green protocol is described for the preparation of a -amino phosphonates, employing a one-pot three-component condensation reaction between aldehydes, amines, and trialkyl phosphites in the presence of PPA-SiO2 under solvent-free conditions at 80 °C. The present procedure offer advantages such as high to excellent yields, short reaction time, inexpensiveness, recovery, and reusability of catalyst.
