• A practical synthesis of substituted 2,6-diaminopyridines via microwave-assisted copper-catalyzed amination of halopyridines

  selective substitution of one or two halogens by aryl or alkylamines was achieved within 2–6 h with temperatures between 80 and 225 °C affording 2,6-diaminopyridines in good to excellent isolated yields. The reaction allows easy variation between educts and different N-substitutions. The target compounds are valuable precursors for the synthesis of bis-phosphorylated 2,6-diaminopyridines which are

• Transition metal-free amination of aryl halides—A simple and reliable method for the efficient and high-yielding synthesis of N-arylated amines

  intermediates is not necessary, allowing the synthesis of pyridine-2,6-diamines in ‘one-pot’. However, catalysts are in many cases not required to efficiently and selectively couple aryl halides with amines, making transition metal-free versions of the Buchwald–Hartwig reaction extremely attractive for the synthesis of N-arylated amines with substrates containing substituents on the aryl halide, which either promote

  提出了一种简单，可靠的反应方案，用于在无过渡金属的反应条件下，由芳基卤化物与各种（也是位阻的）胺反应衍生而来的各种N-芳基化胺的清洁，快速和高产率合成。二恶烷和KN（Si（CH 3）3）2被发现是该转化的理想溶剂和基础。观察到的转化率和产率极好，并且在大多数反应中进行的反应明显高于其催化形式的反应。此外，几乎可以选择性合成6-卤代吡啶-2-胺和不对称吡啶-2,6-二胺（分别来自2,6-二溴吡啶和2,6-二氯吡啶的连续反应）。在非常短的反应时间内即可获得定量收率（相对于2,6-二卤代吡啶）。不需要纯化6-卤代吡啶-2-胺中间体，从而可以在“一锅法”中合成吡啶-2,6-二胺。但是，催化剂在许多情况下不是有效地和选择性地使芳基卤化物与胺偶联，使无过渡金属形式的Buchwald-Hartwig反应对于合成N-芳基化胺（在芳基卤化物上具有取代基的底物）极具吸引力，这会促进区域选择性和/或不需要区域选择性胺化。
• Palladium-Catalyzed Selective Amination of Haloaromatics on KF-Alumina Surface
  作者：Basudeb Basu、Pralay Das、Ashish Nanda、Sajal Das、Sajal Sarkar

  DOI：10.1055/s-2005-865241

  日期：——

  An efficient palladium-catalyzed amination, including polyaminations of aromatic bromides mediated on a surface of KF-alumina, is reported. The solvent-free one-pot protocol avoids the use of a strong base (sodium tert-butoxide) making it applicable to substrates containing a base-sensitive functional group. It proceeds without concomitant reductive bromination and provides access to selective amination of polyhaloaromatics.

  报道了一种高效的钯催化胺化反应，包括在KF-氧化铝表面介导的芳香溴化物的多胺化反应。该无溶剂一步法方案避免了强碱（叔丁醇钠）的使用，使其适用于含有碱敏感官能团的底物。该反应无需伴随还原性溴化作用，能够实现对多卤代芳香化合物的高选择性胺化反应。

• Synthesis and structural characterization of palladium(II) thiosemicarbazone complex: application to the Buchwald–Hartwig amination reaction
  作者：Rupesh Narayana Prabhu、Rengan Ramesh

  DOI：10.1016/j.tetlet.2012.12.070

  日期：2013.2

  A simple route to synthesize mononuclear palladium(II) thiosemicarbazone complex has been described. Elemental analysis, spectral methods and single crystal X-ray diffraction analysis were used to confirm the composition of the complex. The new complex acts as an active homogeneous catalyst for the Buchwald-Hartwig amination reaction of a wide range of aryl and heteroaryl halides (bromides and chlorides), including activating, neutral and deactivating substrates, with various secondary amines under optimized conditions.
