A novel electrophilic-type trifluoromethylthiolation reagent, a trifluoromethanesulfonyl hypervalent iodonium ylide, was designed and reacted well with various nucleophiles to afford the desired CF3S-substituted products. In situ reduction of the trifluoromethanesulfonyl group to give the trifluoromethylthio group, which is the key step in this process, was realized in the presence of copper(I) chloride
设计了一种新型的亲电型三氟甲硫基化试剂,一种三氟甲磺酰基高价碘鎓叶立德,并与各种亲核试剂反应良好,得到所需的 CF3S 取代产物。三氟甲磺酰基的原位还原得到三氟甲硫基,这是该过程中的关键步骤,是在氯化铜 (I) 存在下实现的。
