PhI(OTf) has been used for the past 30 years as a strong I(III) oxidant for organic and inorganic transformations. It has been reported to be generated in situ from the reactions of either PhI(OAc) or PhI=O with two equivalents of trimethylsilyl trifluoromethanesulfonate (TMS-OTf). In this report it is shown that neither of these reactions generate a solution with spectroscopic data consistent with PhI(OTf) , with supporting theoretical calculations, and thus this compound should not be invoked as the species acting as the oxidant for transformations that have been associated with its use.
在过去30年中，二醋酸碘苯（PhI(OTf)）一直被用作一种强三价碘（I(III)）氧化剂，用于有机和无机转化反应。据报道，它可由二醋酸碘苯（PhI(OAc)）或二氧碘苯（PhI=O）与两当量的三甲基甲硅烷基三氟甲磺酸酯（TMS-OTf）反应原位生成。本报告表明，这些反应均未生成具有与二醋酸碘苯（PhI(OTf)）相符的光谱数据的溶液，理论计算也提供了支持，因此，在那些与使用该化合物相关的转化反应中，不应将其作为起氧化剂作用的物种。
