• Rh(I)-Catalyzed Arylation of Heterocycles via C−H Bond Activation:  Expanded Scope through Mechanistic Insight
  作者：Jared C. Lewis、Ashley M. Berman、Robert G. Bergman、Jonathan A. Ellman

  DOI：10.1021/ja0748985

  日期：2008.2.1

  A practical, functional group tolerant method for the Rh-catalyzed direct arylation of a variety of pharmaceutically important azoles with aryl bromides is described. Many of the successful azole and aryl bromide coupling partners are not compatible with methods for the direct arylation of heterocycles using Pd(0) or Cu(I) catalysts. The readily prepared, low molecular weight ligand, Z-1-tert-butyl-2

  描述了一种实用的、官能团耐受的方法，用于各种药学上重要的唑类与芳基溴化物的 Rh 催化直接芳基化。许多成功的唑和芳基溴偶联伙伴与使用 Pd(0) 或 Cu(I) 催化剂直接芳基化杂环的方法不兼容。容易制备的低分子量配体 Z-1-叔丁基-2,3,6,7-四氢膦以双齿 P-烯烃方式与 Rh 配位，提供高活性但热稳定的芳基化催化剂，是这种方法的成功至关重要。通过使用相应鏻的四氟硼酸盐，反应可以在手套箱外组装，无需纯化试剂或溶剂。反应也在四氢呋喃或二恶烷中进行，与大多数其他使用高沸点酰胺溶剂直接芳基化唑类的方法相比，这大大简化了产品的分离。反应在微波反应器中加热进行，在 2 小时内获得优异的产品收率。

Here, we introduce a protocol by which the metalating agent, a disodium-monomagnesium alkyl-amide, forms a template that extends regioselectivity to more distant arene sites.
