Surface-mediated solid-phase reactions: the preparation of acyl phosphonates by oxidation of 1-hydroxyphosphonates on the solid surface

Alumina-supported CrO3, under solvent-free conditions, was found to be an efficient oxidizing reagent for the preparation of acyl phosphonates from 1-hydroxyphosphonates. This method is an easy, rapid, and high-yielding reaction for the preparation of acyl phosphonates from 1-hydroxyphosphonates.
