  Copper-Catalyzed Trifluoromethylation of Aryl and Vinyl Boronic Acids with An Electrophilic Trifluoromethylating Reagent

  摘要：

  A copper-catalyzed trifluoromethylation of aryl- and alkenylboronic acids with Togni's reagent was described. The reaction proceeded in good to excellent yields for a range of different substrates including heteroarylboronic acids and substrates with a variety of functional groups under mild reaction conditions.

  continuous‐flow method for the regioselective arylation of fluoroarenes and fluoropyridines has been developed. The telescoped procedure reported here consists of a three‐step metalation, zincation, and Negishi cross‐coupling sequence, providing efficient access to a variety of functionalized 2‐fluorobiaryl products. Precise temperature control of the metalation step, made possible by continuous‐flow technology

  已经开发出一种连续流方法，用于氟代芳烃和氟吡啶的区域选择性芳基化。此处报道的伸缩程序包括三个步骤的金属化，镀锌和Negishi交叉耦合序列，可有效访问各种功能化的2-氟联芳基产品。连续流技术可以实现对金属化步骤的精确温度控制，从而可以高产率，短停留时间高效制备芳基化产物。另外，还提供了苯并三氟化物衍生物的区域选择性芳基化的几个实例。

  Copper-mediated trifluoromethylation of unsaturated organotrifluoroborates with the Langlois reagent (NaSO2CF3) and TBHP allows the introduction of trifluoromethyl groups into a variety of organic substructures. The reactions are easy to set up, the conditions are mild and general, and the process provides access to trifluoromethylated alkynes, alkenes, arenes, and heteroarenes in fair to good yields
