A multi‐talented system: An efficient copper‐catalyzed tandem trifluoromethylation/annulation of an electron‐deficient aromatic ring has been developed. This method provides a powerful and straightforward way to synthesize trifluoromethylated 1,2‐benzothiazinane dioxides under mild conditions (see scheme). The mechanism was investigated by a series of kinetic experiments and isotopic labeling studies
多才多艺的系统:已开发出一种有效的铜催化串联的三氟甲基化/电子缺陷型芳香环的环。该方法提供了一种在温和的条件下合成三氟甲基化的1,2-苯并噻嗪烷二氧化物的强大而直接的方法(请参见方案)。通过一系列动力学实验和同位素标记研究研究了该机制。
