  摘要：

  Syntheses of (4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)arenes through the Pd-catalyzed borylation of arylbromides with the successive use of 2,2'-bis(1,3,2-benzodioxaborole) and pinacol were investigated. PdCl2(dppf) and AcOK in EtOH or DMSO successfully provided (4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)arenes. In particular, this method was more effective in the borylation of arylbromides bearing sulfonyl groups than the conventional Pd-catalyzed borylation using pinacolborane or bis(pinacolato)diboron.

• Catalytic Boration of Alkyl Halides with Borane without Hydrodehalogenation Enabled by Titanium Catalyst
  作者：Xianjin Wang、Penglei Cui、Chungu Xia、Lipeng Wu

  DOI：10.1002/anie.202100569

  日期：2021.5.25

  titanium‐catalyzed boration of alkyl (pseudo)halides (alkyl‐X, X=I, Br, Cl, OMs) with borane (HBpin, HBcat) is reported. The use of titanium catalyst can successfully suppress the undesired hydrodehalogenation products that prevail using other transition‐metal catalysts. A series of synthetically useful alkyl boronate esters are readily obtained from various (primary, secondary, and tertiary) alkyl electrophiles,

  据报道，钛与硼烷（HBpin，HBcat）形成了空前的，普通的钛催化的硼化烷基（伪）卤化物（烷基X，X = I，Br，Cl，OMs）。使用钛催化剂可以成功地抑制使用其他过渡金属催化剂时普遍存在的不希望的加氢脱卤产物。从各种（伯，仲和叔）烷基亲电试剂（包括未活化的烷基氯）可以容易地获得一系列合成上有用的烷基硼酸酯，并且对其他还原性官能团（如酯，烯烃和氨基甲酸酯）具有耐受性。对该机理的初步研究揭示了可能的自由基反应途径。我们的策略进一步扩展到芳基溴化物也得到了证明。
• Cobalt-Catalyzed Regioselective Borylation of Arenes: N-Heterocyclic Silylene as an Electron Donor in the Metal-Mediated Activation of C−H Bonds
  作者：Hailong Ren、Yu-Peng Zhou、Yunping Bai、Chunming Cui、Matthias Driess

  DOI：10.1002/chem.201605937

  日期：2017.4.27

  C−H Borylation of arenes has been a subject of great interest recently because of its atom‐economy and the wide applicability of borylated products in value‐added synthesis. A new bis(silylene)cobalt(II) complex bearing a bis(N‐heterocyclic silylene)‐pyridine pincer ligand (SiNSi) has been synthesized and structurally characterized. It enabled the regioselective catalytic C−H borylation of pyridines

  由于芳烃的原子经济性和硼酸盐化产物在增值合成中的广泛应用，近年来，芳烃的CH硼化已引起人们极大的兴趣。合成了一种新的带有双（N-杂环甲硅烷基）-吡啶钳式配体（SiNSi）的双（甲硅烷基）钴（II）配合物，并对其结构进行了表征。它使吡啶，呋喃和氟化芳烃的区域选择性催化CH硼化成为可能。值得注意的是，与以前已知的催化体系相比，它对氟化芳烃的硼化具有互补的区域选择性，这表明N杂环亚甲硅烷基供体在金属催化的催化应用中具有巨大的潜力。

  Conducting low‐temperature organometallic reactions under continuous flow conditions offers the potential to more accurately control exotherms and thus provide more reproducible and scalable processes. Herein, progress towards this goal with regards to the lithium–halogen exchange/borylation reaction is reported. In addition to improving the scope of substrates available on a research scale, methods

  is used to n-dope a series of NDI derivatives of varying energy levels. We demonstrate a photoinduced, intermolecular redox-doping process in which a dimethylpropyl amine side chain attached to one NDI reduces another NDI derivative to form radical anions. The influence of the aromatic core substituents on energy levels, doping efficacy and radical anion stability is studied by cyclic voltammetry,

  带有叔胺侧链的萘二酰亚胺（NDI）用于对一系列能级不同的NDI衍生物进行n掺杂。我们证明了光诱导的分子间氧化还原掺杂过程，其中连接到一个NDI的二甲基丙胺侧链还原了另一个NDI衍生物以形成自由基阴离子。通过循环伏安法，UV-Vis和电子顺磁共振（EPR）光谱研究了芳族核取代基对能级，掺杂效率和自由基阴离子稳定性的影响。通常，NDI的HOMO能级负责掺杂过程，而LUMO负责所产生的自由基阴离子的空气稳定性。具有两个氰基取代基的最缺乏电子的NDI衍生物显示出最高的掺杂产率，并产生光和热诱导掺杂的空气稳定的自由基阴离子。
