The reaction of diaryliodonium salts with difluoromethyltriflate in the presence of TBAT and CuTC gave the corresponding trifluoromethylated arenes in moderate yields. Compared to other difluorocarbene-derived trifluoromethylation reactions, the current one proceeded at mild reaction conditions (room temperature) within short reaction time (5 min).
在TBAT和CuTC存在下,二芳基碘鎓盐与三氟甲基三氟甲磺酸盐的反应以中等收率得到了相应的三氟甲基化的芳烃。与其他二氟卡宾衍生的三氟甲基化反应相比,当前的反应在较短的反应时间(5分钟)内在温和的反应条件(室温)下进行。
