Abstract

Abstract Magnetic nanoparticle Fe 3 O 4-immobilized guanidine (MNPs-Guanidine) as a novel magnetically interphase nanocatalyst was synthesized and characterized. MNPs- Guanidine catalyzed the synthesis of α-hydroxyphosphonates from aldehydes and dimethyl phosphite in solvent-free condition at 80 C. The synthesis of α-acetoxyphosphonates through a one-pot reaction of aldehydes, dimethyl phosphite and acetic anhydride was ...
