  使用大块双芳基膦配体和钯环预催化剂实现温和且高选择性的钯催化氨单芳基化

  摘要：

  描述了一种 Pd 催化的氨与多种芳基和杂芳基卤化物的芳基化方法，包括具有挑战性的五元杂环底物。通过使用庞大的联芳膦配体（L6、L7和L4）及其相应的氨基联苯钯环预催化剂（3a、3b和3c），在温和条件下或在室温下实现了将氨单芳基化成伯芳胺的出色选择性。由于该过程既不需要使用手套箱，也不需要高压氨，因此应广泛适用。

• A General Method for Suzuki–Miyaura Coupling Reactions Using Lithium Triisopropyl Borates
  作者：Matthias A. Oberli、Stephen L. Buchwald

  DOI：10.1021/ol302063g

  日期：2012.9.7

  Conditions for the Suzuki–Miyaura coupling of lithium triisopropyl borates are reported, as well as a procedure for a one-pot lithiation, borylation, and subsequent Suzuki–Miyaura coupling of various heterocycles with aryl halides. These borate species are much more stable toward protodeboronation than the corresponding boronic acids and can conveniently be stored on benchtop at room temperature.
