Magnetic-nanoparticle-supported phosphotungstic acid has been used to efficiently catalyze the hydrophosphonylation reaction of isatins, imines, and aldehydes using dimethyl and diethyl phosphite as a nucleophile to give the corresponding α-hydroxy and α-amino phosphonates in excellent yields for a wide range of substrates. The reaction conditions were simple, green, and efficient. The catalyst was recycled up to five times with retention of its activity. Based on the NMR spectroscopy studies, a probable catalytic cycle was proposed.

A simple, efficient, and general method has been developed for the synthesis of α-aminophosphonates in the presence of solid lithium perchlorate under solvent-free conditions. Thus secondary and tertiary α-aminophosphonates were synthesized relatively quickly in good yields at room temperature. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003.
