trifluoromethylation via AgI/AgIII redox shuttles are herein deciphered. This innovative cross-coupling, analogous to the CEL coupling popularized by copper, involves: i) easy AgI/AgIII 2e− oxidation; ii) phen ligation to AgIII; iii) boron-to-AgIII aryl transfer; and iv) benzotrifluoride production from aryl-AgIII intermediates. Now, AgIIICF3 chemistry is safe and reachable from AgF, KF, CF3TMS and air.
教银做伎俩。通过Ag I / Ag III氧化还原穿梭进行氧化三氟甲基化的最关键步骤在本文中被破译。这种创新的交叉耦合类似于铜普及的 CEL 耦合,包括:i)容易的 Ag I /Ag III 2 e -氧化;ii)苯连接到 Ag III 上;iii)硼到 Ag III芳基转移;和ⅳ)三氟甲苯产量从芳基的Ag III中间体。现在,Ag III CF 3化学是安全的,可以从 AgF、KF、CF 3 TMS 和空气中获得。
