  [Ru3(CO)12] and AgO2C(1-Ad) enabled the first ruthenium-catalyzed intermolecular halogenations of arenes via C–H activation. Thereby, brominations and iodinations of electron-rich and electron-deficient benzamides were achieved in a highly selective fashion.

  EtOTf and LiAlH(OEt)3 in the absence of base were found to be optimal for reducing extremely sterically demanding 2,6-disubstituted N,N-diisopropylbenzamides. The reaction tolerates various reducible functional groups, including aldehyde and ketone. 1H NMR studies confirmed the formation of imidates stable in water. The synthetic usefulness of this methodology was demonstrated with N,N-diisopropylamide-directed

  已经开发出一种用于化学选择性地将空间上需要的N，N-二异丙基酰胺还原成醛的顺序一锅法。在该反应中，酰胺用EtOTf活化形成酰亚胺，然后用LiAlH（OR）3 [R = t- Bu，Et]还原，通过水解所得到的半缩醛产生醛。非亲核碱基2,6-DTBMP显着提高了反应效率。发现EtOTf / 2，6-DTBMP和LiAlH（O- t- Bu）3的组合对于还原烷基，烯基，炔基和2-单取代的芳基N，N-二异丙基酰胺是最佳的。相反，EtOTf和LiAlH（OEt）3在没有碱的情况下，发现其对于还原空间上要求极高的2，6-二取代的N，N-二异丙基苯甲酰胺是最佳的。该反应可耐受各种可还原的官能团，包括醛和酮。1 H NMR研究证实了在水中稳定形成的酰亚胺。这种方法的综合实用性通过N，N-二异丙基酰胺定向的邻位金属化和CH键的活化得到了证明。

  aliphatic substrates for selective C(sp3)–H bond borylations. Heterocyclic molecules are selectively borylated using the inherently elevated reactivity of the C–H bonds. A number of late-stage C–H functionalization have been described using the same catalysts. Furthermore, we show that one of the catalysts could be used even in open air for the C(sp2)–H and C(sp3)–H borylations enabling the method more general

  在这里，我们描述了一类新的 C-H 硼化催化剂的发现及其在芳族、杂芳族和脂肪族系统的区域选择性 C-H 硼化中的应用。新催化剂具有 Ir-C(噻吩基) 或 Ir-C(呋喃基) 阴离子配体，而不是标准 C-H 硼化条件中使用的二胺型中性螯合配体。据报道，这些新发现的催化剂的使用对不同种类的芳烃底物显示出优异的反应性和邻位选择性，并具有高分离产率。此外，该催化剂被证明对大量脂肪族底物的选择性 C(sp 3)–H 键硼化。杂环分子利用 C-H 键固有的高反应性选择性地硼化。已经使用相同的催化剂描述了许多后期 C-H 功能化。此外，我们表明其中一种催化剂甚至可以在露天用于 C(sp 2 )-H 和 C(sp 3 )-H 硼酸化，从而使该方法更加通用。初步的机理研究表明，活性催化中间体是 Ir(bis)boryl 络合物，连接的配体作为双齿配体。总的来说，这项研究强调了新型 C-H 硼酸化催化剂的发现，这些催化剂应该在
• Amide Effects in C−H Activation: Noncovalent Interactions with L-Shaped Ligand for <i>meta</i> Borylation of Aromatic Amides
  作者：Ranjana Bisht、Md Emdadul Hoque、Buddhadeb Chattopadhyay

  DOI：10.1002/anie.201809929

  日期：2018.11.26

  A new concept for the meta‐selective borylation of aromatic amides is described. It has been demonstrated that while esters gave para borylations, amides lead to meta borylations. For achieving high meta selectivity, an L‐shaped bifunctional ligand has been employed and engages in an O⋅⋅⋅K noncovalent interaction with the oxygen atom of the moderately distorted amide carbonyl group. This interaction

  描述了芳族酰胺间选择性硼化的新概念。已经证明，尽管酯产生对硼烷基化，但是酰胺导致间硼烷基化。为了实现较高的间位选择性，使用了L型双功能配体，该配体与中度扭曲的酰胺羰基的氧原子发生O⋅⋅⋅K非共价相互作用。这种相互作用提供了对元CH活化/基化的特殊控制。
