A sub-stoichiometric Tf2O/DMSO-mediated cooxidation approach has been developed for the efficient oxidation of phosphines to phosphine oxides. By avoiding the use of stoichiometric oxidants or toxic reagents, this procedure provides an economical and practical route to a variety of phosphine oxides. A broad range of P(III)-compounds are well compatible with this transformation. The mild conditions, short reaction time, and scale-up preparation enable the potential application of this method to the late-stage industrial production.

Key words: phosphorus chemistry, sub-stoichiometric, cooxidation, tertiary phosphine oxides
