Nanosize magnetic particles coated with magnesium oxide (core/shell nanoparticles) have been prepared and used for the synthesis of 1-hydroxyalkyl phosphonates. Catalytic activity studies show that the magnetic particles coated with magnesium oxide have highly catalytic activity toward the phosphorylation of aldehydes for the synthesis of 1-hydroxyalkyl phosphonates under solvent-free conditions. Reusability of the prepared magnetic nanoparticles was successfully examined five times with a very slight loss of catalytic activity.
alpha-Hydroxyphosphonates were synthesized from aromatic/heteroaromatic aldehydes with triethyl phosphite in the presence of beta-cyclodextrin in an aqueous medium. The beta-cyclodextrin can be recovered and reused without loss of catalytic activity.
