A Methodology Study of Hydrophosphonylation of Aldehydes Derivatives with H6P2W18O62•14H2O as a Catalyst

Abstract

A catalytic process for hydrophosphonylation of aldehydes with H6P2W18O62·14H2O has been developed in this paper. Various aldehydes were reacted with diethylphosphite in the presence of 1 % of heteropolyacids (HPAs) as a catalyst to generate the α-hydroxyphosphonates. All the synthesized compounds were sys tematically characterized by IR, H NMR, C NMR, and P NMR. Simple and mild method, short reaction time, solvent-free conditions, availability and reusability of the catalyst are the main advantages of this procedure.
