  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

  Pd–PEPPSI complexes were designed and synthesized. The relationship between catalyst structure and properties was systematically investigated. It was revealed that “bulky‐yet‐flexible” C3 bearing ancenaphthyl backbone was a highly efficient precatalyst and could be successfully employed in Suzuki–Miyaura reactions of (hetero)aryl chlorides with (hetero)arylboronic acids at a low palladium loading in the presence

  C1–C5, bearing dianisole backbones and substituted N-aryl moieties have been synthesized and characterized. The electronic effect as well as the steric environment of the NHC ligands has been assessed. The synthesized palladium complexes were applied for Suzuki–Miyaura cross-coupling reactions under aerobic conditions. The relationship between the catalytic structure and catalytic performance was then
