    摘要:
    通过外部氢转移介导的活化模式,我们在本文中证明了新的钯催化的不同类型的N-杂芳烃的直接α,β-偶联。这样的选择性偶合反应具有操作简单,原子经济效率高以及使用安全和丰富的异丙醇作为活化剂的优点,提供了接近氮双杂芳烃的实用方法。初步研究表明,所获得的bis-1,10-菲咯啉2qq'作为配体能够改善形成C-C键的铜催化剂。本文报道的工作为建立扩展的π共轭体系奠定了重要基础,该体系在生物学,药物,材料和合成有机化学以及催化方面具有重要意义。

    Reductive functionalization of N-heteroarenes remains to date a challenge due to the easy occurrence of direct reduction of such substances into non-coupling saturated cyclic amines. Herein, by developing an unprecedented manganese catalyst ligating with an unsymmetrical 2-aminotetrahydronaphthyridyl PNP-ligand, we have achieved a new reductive cross-coupling of indoles/pyrroles and N-heteroarenes
    迄今为止,N-杂芳烃的还原功能化仍然是一个挑战,因为这种物质容易直接还原成非偶联的饱和环胺。在此,通过开发与不对称的2-氨基四氢萘吡啶基PNP-配体连接的史无前例的锰催化剂,我们实现了吲哚/吡咯与N-杂芳烃的新的还原交叉偶联。机理研究表明,催化剂能够原位活化通过中断N-杂芳烃的第二次转移氢化来捕获部分还原的中间体构成了本反应成功的关键。所开发的化学方法具有良好的底物和官能团相容性,较高的步长和原子效率,优异的化学和区域选择性,并适用于含吡啶生物医学分子的后期修饰,从而建立了一个新的平台,使芳香族系统可以连接到功能框架,以及不对称PNP有机金属配合物和相关催化转化的进一步发展。

  • Understanding C–H Bond Activation on a Diruthenium(I) Platform

    Activation of the C-H bond at the axial site of a [Ru-I-Ru-I] platform has been achieved. Room-temperature treatment of 2-(R-phenyl)-1,8-naphthyridine (R = H, F, OMe) with [Ru-2(CO)(4)(CH3CN)(6)][BF4](2) in CH2Cl2 affords the corresponding diruthenium(I) complexes, which carry two ligands, one of which is orthometalated and the second ligand engages an axial site via a Ru center dot center dot center dot C-H interaction. Reaction with 2-(2-N-methylpyrrolyl)-1,8-naphthyridine under identical conditions affords another orthometalated/nonmetalated (om/nm) complex. At low temperature (4 degrees C), however, a nonmetalated complex is isolated that reveals axial Ru center dot center dot center dot C-H interactions involving both ligands at sites trans to the Ru-Ru bond. A nonmetalated (nm/nm) complex was characterized for 2-pyrrolyl-1,8-naphthyridine at room temperature. Orthometalation of both ligands on a single [Ru-Ru] platform could not be accomplished even at elevated temperature. X-ray metrical parameters clearly distinguish between the orthometalated and nonmetalated ligands. NMR investigation reveals the identity of each proton and sheds light on the nature of [Ru-Ru]center dot center dot center dot C-H interactions (preagostic/agostic). An electrophilic mechanism is proposed for C-H bond cleavage that involves a C(p(pi))-H -> sigma* [Ru-Ru] interaction, resulting in a Wheland-type intermediate. The heteroatom stabilization is credited to the isolation of nonmetalated complexes for pyrrolyl C-H, whereas lack of such stabilization for phenyl C-H causes rapid proton elimination, giving rise to orthometalation. NPA charge analysis suggests that the first orthometalation makes the [Ru-Ru] core sufficiently electron rich, which does not allow significant interaction with the other axial C-H bond, making the second metalation very difficult.
