• Mild and General Conditions for Negishi Cross-Coupling Enabled by the Use of Palladacycle Precatalysts
  作者：Yang Yang、Nathan J. Oldenhuis、Stephen L. Buchwald

  DOI：10.1002/anie.201207750

  日期：2013.1.7

  A wide range of biaryls were synthesized by palladium‐catalyzed Negishi cross‐couplings at ambient temperature or with low catalyst loading. This protocol features the use of a recently reported aminobiphenyl palladacycle precatalyst to generate the catalytically active XPhosPd0 species. Significantly, a wide range of challenging heterocyclic and polyfluorinated aromatic substrates can be employed

  在环境温度或低催化剂负载量下，通过钯催化的根岸交叉偶联合成了多种联芳基化合物。该协议的特点是使用最近报道的氨基联苯钯环预催化剂来生成具有催化活性的 XPhosPd 0物质。值得注意的是，可以采用各种具有挑战性的杂环和多氟化芳香族底物来获得高产率的产品。
