We report a continuous-flow protocol for the trifluoromethylation of arenes, heteroarenes, and benzofused heterocycles. This photoredox methodology relies on the use of solid sodium trifluoromethanesulfinate (CF3SO2Na) as the trifluoromethylating agent and the iridium complex [IrdF(CF3)ppy}2](dtbpy)]PF6 as the photoredox catalyst. A diverse set of highly functionalized heterocycles proved compatible with the methodology, and moderate to good yields were obtained within 30 minutes of residence time.
我们报告了一种用于芳烃、杂环化合物和苯并杂环化合物三氟甲基化的连续流程。这种光氧还原方法依赖于固体三氟甲磺酰亚铁钠(CF3SO2Na)作为三氟甲基化试剂,以及铱配合物[IrdF(CF3)ppy}2](dtbpy)]PF6作为光氧还原催化剂。多样化的高度官能化杂环化合物证明与该方法兼容,并且在30分钟的停留时间内获得了中等至良好的产率。
