silver‐promoted oxidative benzylic C−H trifluoromethoxylation has been reported for the first time. With trifluoromethyl arylsulfonate as the trifluoromethoxylation reagent, various arenes, having diverse functional groups, undergo trifluoromethoxylation of their benzylic C−H bonds to form trifluoromethyl ethers under mild reaction conditions. In addition, the trifluoromethoxylation and the fluorination of methyl
首次报道了银促进的氧化苄基CH三氟甲氧基化反应。用三氟甲基芳基磺酸盐作为三氟甲氧基化试剂,具有不同官能团的各种芳烃在温和的反应条件下对其苄基CH键进行三氟甲氧基化,形成三氟甲基醚。此外,已经实现了一步法制备富电子芳烃的三氟甲氧基化和甲基氟化,以制备α-氟苄基三氟甲基醚。
