  摘要：

  描述了将三氟甲基芳烃中的 C(sp3)-F 键氧化加成到镍 (0) 配合物的第一个例子。带有两个低空间位阻要求的 N-杂环卡宾 (NHC) 配体的镍 (0) 配合物能够裂解三氟甲基芳烃的 C(sp3)-F 键，得到相应的反式二氟苄基镍 (II) 氟化物配合物。分离和表征研究表明，C(sp3)-F 键的裂解是通过 η2-芳烃镍 (0) 配合物进行的。利用这些氟化镍 (II) 配合物的反应性，我们开发了一种使用氢硅烷对三氟甲基芳烃进行催化加氢脱氟的方法。一项计算研究表明，由两个相对较小的 NHC 配体支持的富电子镍 (0) 中心通过 syn-SN2' 机制裂解 C(sp3)-F 键。

  strategy for aromatic trifluoromethylation by converting amino into trifluoromethyl groups via a Sandmeyer-type reaction is reported. The transformation involves diazotization of the aromatic amines with tert-butyl nitrite and hydrochloric acid to form aryldiazonium chlorides, followed by trifluoromethylation with trifluoromethylsilver at low temperature. Various readily available aromatic amines are

While SNAr and SRN1 mechanisms are not operational, there is a well-pronounced ortho effect, i.e., the enhanced reactivity of ortho-substituted aryl halides 2-RC6H4X toward CuCF3.
