An efficient alkylation method of functionalized alkyl halides under mild nickel‐catalyzed C(sp3)C(sp2) Suzuki cross‐coupling conditions is described. The features of this approach are excellent functional group compatibility, low cost nickel catalyst, and the use of a mild base. This is also the first successful example of the nickel‐catalyzed direct 2,2‐difluoroethylation or 2,2,2‐trifluoroethylation
描述了一种在轻度镍催化的C(sp 3)C(sp 2)Suzuki交叉偶联条件下官能化烷基卤化物的有效烷基化方法。这种方法的特点是出色的官能团相容性,低成本的镍催化剂以及使用温和的碱。这也是芳基/杂芳基硼酸镍催化的直接2,2-二氟乙基化或2,2,2-三氟乙基化的第一个成功实例。
