  仲烷基溴化物与芳基和烯基三氟甲磺酸酯和壬二酸酯的Barbier-Negishi偶联

  摘要：

  已经开发出温和而实用的仲烷基溴化物与芳基和烯基三氟甲磺酸酯和壬二酸酯的Barbier-Negishi偶联。通过使用非常庞大的咪唑基膦配体，可以实现这一具有挑战性的反应，从而在室温下和非水条件下对多种底物产生了良好的收率以及良好的化学和位点选择性。通过使用类似的吡唑基配体，该反应扩展为伯烷基溴化物。

  zinc bromides and regioconvergent Negishi coupling with aryl or alkenyl triflates. The use of a suitable phosphine ligand favoring Pd migration enabled the selective formation of the linear cross‐coupling product. Subsequently, mixtures of secondary alkyl bromides were prepared from linear alkanes by standard bromination, and regioconvergent cross‐coupling then provided access to the corresponding linear

  碳氢化合物仍然是功能化有机分子的最重要前体，在新型CH键功能化方法的发现中引起了人们的兴趣。我们在这里描述了一种新的步骤经济的方法，该方法使C-C键能够在直链烷烃的末端位置进行构建。首先，我们表明仲烷基溴化物可以原位转化为烷基溴化锌和与会聚芳基或烯基三氟甲磺酸酯的区域收敛的Negishi。使用合适的膦配体促进Pd迁移，可以选择性形成线性交叉偶联产物。随后，通过标准溴化反应，由直链烷烃制备仲烷基溴化物的混合物，然后通过区域会聚交叉偶联，仅需两个步骤即可获得相应的线性芳基化产物。

  Negishi-like cross-couplings between (functionalized) alkyl and aryl bromides are described. Despite the fact that organozinc reagents are intolerant of water, their formation as well as their use in an aqueous micellar environment is discussed herein. Each component of this complex series of events leading up to C–C bond formation has an important role which has been determined insofar as the type

  描述了（功能化的）烷基和芳基溴化物之间的 Negishi 样交叉偶联。尽管有机锌试剂不耐水，但本文讨论了它们的形成以及它们在水性胶束环境中的应用。就锌、胺配体、表面活性剂和钯催化剂的类型而言，这一系列导致 C-C 键形成的复杂事件的每个组成部分都具有重要作用。特别是，已发现表面活性剂的性质对于获得涉及高反应性、湿敏性有机金属化合物的合成有用结果至关重要。发生这些交叉偶联既不需要有机溶剂也不需要热量；就加水。

  secondary alkyl bromides with aryl and alkenyl triflates and nonaflates has been developed. This challenging reaction was enabled by the use of a very bulky imidazole‐based phosphine ligand, which resulted in good yields as well as good chemo‐ and site selectivities for a broad range of substrates at room temperature and under non‐aqueous conditions. This reaction was extended to primary alkyl bromides
