• Non-coordinating-Anion-Directed Reversal of Activation Site: Selective C−H Bond Activation of<i>N</i>-Aryl Rings

  An Rh‐catalyzed selective C−H bond activation of diaryl‐substituted anilides is described. In an attempt to achieve C−H activation of C‐aryl rings, we unexpectedly obtained an N‐aryl ring product under non‐coordinating anion conditions, whereas the C‐aryl ring product was obtained in the absence of a non‐coordinating anion. This methodology has proved to be an excellent means of tuning and adjusting

  描述了二芳基取代的苯甲酰胺的Rh催化的选择性C H键活化。为了实现C-芳基环的CH活化，我们意外地在非配位阴离子条件下获得了N-芳基环产物，而C-芳基环的产物是在不存在非配位阴离子的条件下获得的。事实证明，该方法学是调节和调节C芳基和N选择性C H键活化的极佳方法芳基环。通过机械研究和理论计算使该方法合理化。另外，已经发现并证实，非配位阴离子明显提高了铑催化剂的催化活性，这为获得高化学选择性催化剂提供了有效的策略。机械实验也明确地排除了这种涉及银的转变中所谓的“银效应”的可能性。

  Described herein is an efficient new method for ortho-olefination of anilides in the presence of AgSbF6 and NaOAc via rhodium(III)-catalyzed internal oxidative C-H bond activation based on hydroxyl as directing and oxidative group. A range of alkenes and functional groups on acetanilides is supported and a possible mechanism is proposed according to the experimental results. (C) 2015 Elsevier Ltd. All rights reserved.
• Catalytic Coupling of Haloolefins with Anilides

  A strategy in which C-H activation reactions promoted by Pd(II) have been combined with beta-heteroatom elimination to create a catalytic cycle achieving the arylation of haloacrylates is reported. The catalytic cycle can be subdivided into four parts: (1) C-H activation; (2) the functionalization step, migratory insertion of the olefin into a metal-carbon bond; (3) beta-heteroatom elimination; and (4) exchange of metal halide (if X = halogen) for a less coordinating anion. In this catalytic cycle, the oxidation state of the metal does not change, and an oxidant is not required. The method is more functional group tolerant compared with the existing alkene-arene coupling methods based on electrophilic C-H activation.
