三氟甲基亚砜是一类新型三氟甲基硫醇化试剂。亚砜与一系列(杂)芳烃发生无金属的 C−H 三氟甲硫基化反应。该方法还适用于重要化合物类别的官能化,例如配体衍生物和聚芳烃,以及药物和农用化学品的后期三氟甲硫基化。锍盐中间体的分离和表征支持了间断的普默勒反应机制。 我可以打断一下吗?利用中断的普默勒反应,三氟甲基亚砜参与(杂)芳烃(包括药物分子和天然产物)的无金属 C−H 三氟甲硫基化。这种新型三氟甲基硫基化试剂采用了一种新的三氟甲基硫基化策略,其中锍盐被组装并选择性解构。
Trifluoromethyl sulfoxides are a new class of trifluoromethylthiolating reagent. The sulfoxides engage in metal‐free C−H trifluoromethylthiolation with a range of (hetero)arenes. The method is also applicable to the functionalization of important compound classes, such as ligand derivatives and polyaromatics, and in the late‐stage trifluoromethylthiolation of medicines and agrochemicals. The isolation and characterization of a sulfonium salt intermediate supports an interrupted Pummerer reaction mechanism. May I interrupt? Taking advantage of the interrupted Pummerer reaction, trifluoromethyl sulfoxides engage in the metal‐free C−H trifluoromethylthiolation of (hetero)arenes, including drug molecules and natural products. This new class of trifluoromethylthiolating reagent exploits a new strategy for trifluoromethylthiolation in which sulfonium salts are assembled and selectively deconstructed.
