  Bring it on! An effective Pd‐catalyzed ortho olefination of various acetanilides has been developed. This transformation has a broad substrate scope and wide functional‐group tolerability, regardless of the electronic and steric properties of acetanilide substrates, providing a straightforward access to highly functionalized arenes.

  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。

  Transition-metal-catalyzed aromatic olefination through direct C–H activation represents an atom and step-economic route for versatile pharmaceutical syntheses, and in many cases, different stoichiometric oxidants are frequently employed for achieving a reasonable catalytic efficiency of the transition metal ions. Herein, we report a Lewis acid promoted Pd(II)-catalyzed acetanilide olefination reaction with atmospheric

  通过直接 C-H 活化的过渡金属催化芳烃烯化代表了一种用于多功能药物合成的原子和步骤经济路线，并且在许多情况下，经常使用不同化学计量的氧化剂来实现过渡金属离子的合理催化效率。在此，我们报道了路易斯酸促进的 Pd( II ) 催化的乙酰苯胺烯化反应，以大气分子氧为氧化剂源。路易斯酸通过二乙酸酯桥与 Pd( II ) 物质连接显着提高了其催化效率，并且对烯化步骤的独立动力学研究表明，添加路易斯酸显着加速了烯化速率以及 C-H 活化步。 Pd( II )盐中内部碱的强碱性也可能通过碱辅助的β-氢化物消除有利于烯化反应。

  C-H bond activation is an important issue. The Pd-catalyzed and non-coordinating anion improved C-H bond activation was realized through the oxidative coupling reaction of anilides with olefins under non-acidic conditions. Additionally, the catalytic activity of palladium catalysts is enhanced by non-coordinating anions, further proving that non-coordinating anion can be used in palladium-involved reactions.
