  AlCl3 介导的 CHF2 转移和二氟甲氧基官能化邻苯二胺的环缩合获得 N-取代苯并咪唑

  摘要：

  在此，我们首次报道了不含过渡金属的受挫路易斯对 (FLP) 催化 CHF 2基团从氧原子迁移到相邻的氮原子，从而在室温下合成了具有优异性能的 N-取代苯并咪唑。产率、广泛的官能团耐受性和较短的反应时间。在 AlCl 3存在下，连接氧的二氟甲烷作为 C1 源在合成 N 取代苯并咪唑的过程中通过裂解一个 C-O 键和两个 C-F 键，导致形成两个新的 C-N 键。

  ortho-arylation of benzylamines followed by in situ lactamization. This cascade sequence is enabled by the use of 2-iodobenzoates, which facilitates C-H arylation from the free amine under conditions that typically require an improved directing group approach. This reaction is characterized by a broad substrate scope with good functional group tolerance. The need for an ester versus carboxylic acid-functionalized
