A large number of fluorination methods have been developed, but the construction of a tertiary C–F bond remains challenging. Herein, we describe an efficient dehydroxylative fluorination of tertiary alcohols with Selectfluor via the activation of a hydroxyl group by a Ph2PCH2CH2PPh2/ICH2CH2I system. Although the reagents appear to be not compatible (Selectfluor with the phosphine and I generated in situ), the reactions occur rapidly to give the desired products in moderate to high yields. This work may present a new discovery in fluorination of alcohols since the reported methods are mainly limited to primary and secondary alcohols.

叔醇的脱羟基氟化。

已经开发出了许多氟化方法,但是三次C-F键的构建仍然具有挑战性。在本文中,我们描述了通过Ph 2 PCH 2 CH 2 PPh 2 / ICH 2 CH 2 I系统活化羟基,用Selectfluor有效地进行叔醇的脱羟基氟化反应。虽然试剂似乎是不兼容(的Selectfluor与膦和我-原位产生),快速地发生反应,得到所期望的产物在较高产率。由于报道的方法主要限于伯醇和仲醇,因此这项工作可能会在醇的氟化方面提出新的发现。
