Herein, we report a simple and efficient method for the direct installation of chlorodifluoroethyl group onto aromatic molecules of various aromatic amides with a new 2-chloro,2,2-difluoroethyl(mesityl)iodonium salt (CDFI). Moreover, the chlorodifluoroethyl compounds could be smoothly converted into difluorovinyl compounds in a one-pot or discrete procedure and regarded as a steady source of difluorovinyl
在此,我们报告了一种简单有效的方法,该方法使用新的 2-氯,2,2-二氟乙基(均三甲基)碘鎓盐 (CDFI) 将氯二氟乙基直接安装到各种芳族酰胺的芳族分子上。此外,氯二氟乙基化合物可以在一锅法或离散过程中顺利转化为二氟乙烯基化合物,并被视为具有“HCl-mask”的二氟乙烯基化合物的稳定来源。
