开发了一种亚化学计量Tf2O (三氟甲烷磺酸酐)和DMSO (二甲基亚砜)协同促进的三价磷试剂到三级磷氧化物的高效氧化反应。该反应使用亚化学计量的Tf2O和DMSO作为氧化剂,反应条件温和,反应速率快,在不影响产率的情况下可进行有效的放大,为三级磷氧化物的制备提供了一种高效、实用的方法。该反应展现出良好的底物普适性,多种三价磷试剂在该反应体系下都能良好的兼容。在机理实验的基础上,我们提出了该反应可能同时存在的两种反应路径。

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
