  Electron-Deficient Triphenylene and Trinaphthylene Carboximides

  摘要：

  A series of triphenylene and trinaphthylene carboximides were synthesized mainly through Diels-Alder reactions between the in situ generated radialenes and N-alkylmaleimides. High electron affinity was obtained due to the attachment of electron-withdrawing carboximide groups. These disklike molecules can assemble into one-dimensional columnar structures in solid state and their mesophase properties were characterized by DSC, POM, and X-ray diffraction. Long-range ordered columnar phase was observed, qualifying them as potential n-type semiconductors in electronic devices.

• Highly Efficient Route to Fused Polycyclic Aromatics via Palladium-Catalyzed Aryne Annulation by Aryl Halides
  作者：Zhijian Liu、Richard C. Larock

  DOI：10.1021/jo0619534

  日期：2007.1.1

  Polycyclic aromatic and heteroaromatic hydrocarbons have been synthesized in high yield by two different processes involving the Pd-catalyzed annulation of arynes. The first process involves a Pd-catalyzed annulation of arynes by 2-halobiaryls and related vinylic halides. The second process utilizes a Pd-catalyzed double annulation of arynes by simple aryl halides. Both processes appear to involve

  多环芳族和杂芳族烃已通过涉及钯催化的芳烃环化的两种不同方法以高收率合成。第一个过程涉及2-卤代联芳基和相关的乙烯基卤化物的钯催化芳烃的环化反应。第二种方法是通过简单的芳基卤化物利用Pd催化的芳烃双环。两种方法似乎都涉及两个反应性很强的底物，芳烃和有机钯物质的催化，逐步偶联，以产生优异的交叉偶联产物收率。

  for electron deficient triphenylenes. Here we demonstrate that the nickel-mediated Yamamoto coupling of o-dibromoarenes is a concise and efficient way to prepare substituted triphenylenes, including electron-deficient systems that are otherwise challenging to prepare. We also demonstrate the application of this approach to prepare electron deficient discotic mesogens composed of triphenylenes bearing

  取代的苯并苯作为有机半导体显示出前景，因为它们能够形成具有扩展 π 堆叠阵列的柱状液晶相。虽然有几种制备三亚苯的方法，包括氧化环化反应如 Scholl 反应，以及过渡金属催化的芳烃环三聚，但这些方法对缺电子的三亚苯无效。在这里，我们证明了邻二溴芳烃的镍介导的 Yamamoto 偶联是制备取代苯并苯的一种简洁有效的方法，包括制备具有挑战性的缺电子系统。我们还展示了该方法在制备由带有酰亚胺和硫代酰亚胺基团的苯并三苯组成的缺电子盘状介晶中的应用。

  DDQ/H+ system readily oxidizes a variety of electron donors with oxidation potential as high as ∼1.7 V to the corresponding cation radicals. A re-examination of the controversial arenium-ion versus cation-radical mechanisms for Scholl reaction using DDQ/H+ together with commonly utilized FeCl3 as oxidants led us to demonstrate that the reaction proceeds largely via a cation-radical mechanism. The critical

  DDQ / H +系统易于将各种电子供体氧化，氧化电位高达1.7 V，可氧化成相应的阳离子自由基。使用DDQ / H +和常用的FeCl 3作为氧化剂对Scholl反应中有争议的氢离子与阳离子自由基机理的重新检验，使我们证明反应主要是通过阳离子自由基机理进行的。支持Scholl反应的阳离子自由基途径的重要实验证据包括：（i）在二氯甲烷和各种酸（10％v / v）的混合物中，Scholl前体中没有反应。（ii）必须使用强氧化剂，例如氯化铁（FeCl 3）或DDQ / H +考虑到二氢中间体的芳构化（通过芳烃离子机理形成）可以很容易地用相当弱的氧化剂（例如碘或空气）来完成，因此Scholl反应与芳烃离子机理不一致。（iii）与SCE相比，氧化电位≤1.7V的各种Scholl前体易于形成DDQ / H +作为氧化剂的C-C氧化键，而与SCE相比，氧化电位大于1.7 V的Scholl前体则不会发生

  Electrochemical nickel-catalyzed syntheses of triphenylenes by a) reductive trimerization of ortho-dibromobenzenes or ortho-bromoarylsulfurofluoridates, or b) reductive cross-coupling of ortho-dibromobenzenes to 2,2’-diiodobiphenyls, are described. The former provides a practical means for the construction of triphenylene derivatives in up to 87% isolated yield at room temperature. For 1,2-dihalo-3-methylbenzenes

• Oxidative C−C Bond Formation (Scholl Reaction) with DDQ as an Efficient and Easily Recyclable Oxidant
  作者：Linyi Zhai、Ruchi Shukla、Rajendra Rathore

  DOI：10.1021/ol901331p

  日期：2009.8.6

  DDQ in the presence of an acid is known to oxidize a variety of aromatic donors to the corresponding cation radicals. Herein, we now demonstrate that the DDQ/H+ system can be effectively utilized for the oxidative C-C bond formations or biaryl synthesis. The efficient preparation of a variety of polyaromatic hydrocarbons including graphitic hexa-peri-hexabenzocoronenes, ease of isolation of the clean products, and ready regeneration of DDQ from easily recovered reduced DDQ-H-2 advances the use of DDQ/H+ for Scholl reactions.
