  铁催化的C ？H键活化与格利雅试剂的芳基吡啶和亚胺的邻位芳构化

  摘要：

  所述的芳基化直接邻-C 芳吡啶或与芳基格氏试剂的芳亚胺H键已经通过使用铁二胺催化剂和二氯烷烃如在短的反应时间的氧化剂来实现（例如，5分钟）在温和的条件下（0°C）。使用芳族助溶剂（例如氯苯和苯）以及缓慢添加格氏试剂对于提高反应效率至关重要。与使用芳基锌试剂的先前开发的反应相比，本芳基化反应具有明显的优点，例如其反应速率和原子经济性。选择性C在离去基团例如对甲苯氧基，氯和溴基的存在下发生H键活化。化学计量反应和动力学同位素效应的研究为反应中间体和CH键活化步骤提供了启示。

  The Rh(I)-catalyzed direct reorganization of organic frameworks and group exchanges between carboxylic acids and aryl ketones was developed with the assistance of directing group. Biaryls, alkenylarenes, and alkylarenes were produced in high efficiency from aryl ketones and the corresponding carboxylic acids by releasing the other molecule of carboxylic acids and carbon monoxide. A wide range of functional

  bond was developed using aryl acylperoxides as inexpensive aryl sources. Substrates containing pyridyl, oxime, and oxazoline groups undergo effectively ortho-selective C−H arylation with excellent functional group tolerance. This arylation should begin by directing-group-assisted cyclopalladation, followed by the reaction of the palladacycle with aryl radicals generated in situ by thermal decomposition

  The rhodium(I)‐catalyzed extrusion of carbon monoxide from biaryl ketones and alkyl/alkenyl aryl ketones was developed to produce biaryls and alkyl/alkenyl arenes, respectively, in high yields (see scheme). A wide range of functionalities are tolerated. Not only does this method provide an alternative pathway to construct useful scaffolds, but also offers a new strategy for CC bond activation.

• Catalytic and Highly Regioselective Cross-Coupling of Aromatic C−H Substrates
  作者：Kami L. Hull、Melanie S. Sanford

  DOI：10.1021/ja074395z

  日期：2007.10.1

  This communication describes a new Pd-catalyzed reaction for the highly chemo- and regioselective oxidative cross-coupling of aromatic C-H bonds. This transformation is proposed to proceed via two discrete C-H activation steps whose selectivities are predominantly controlled by proximity to a ligand (first C-H activation) or by the steric environment around the arene C-H bond (second C-H activation). Furthermore, the selectivity of the second C-H activation reaction can be controlled by tuning the ligand environment around the Pd center.
