• Iridium Catalysis for CH Bond Arylation of Heteroarenes with Iodoarenes
  作者：Benoît Join、Takuya Yamamoto、Kenichiro Itami

  DOI：10.1002/anie.200806358

  日期：2009.5.4

  Efficient couplings using equimolar quantities of each coupling partner and multiple CH bond arylation reactions are achieved with an Ir‐based catalytic system for the CH bond arylation of electron‐rich heteroarenes with iodoarenes to construct extended π‐systems. The dramatic ligand effect on reaction efficiency leads to the discovery that Crabtree's catalyst (see scheme) is the optimal catalyst

• Use of simple test reactions to characterise the catalytic activity of a commercial CoO-MoO3-Al2O3 catalyst

  Exchange of thiophene with D2 and reactions of deuterium-labelled propene and isobutene, followed using a combination of mass spectrometry and microwave spectroscopy, have been used to characterise the catalytic nature of a commercial CoO-MoO3-Al2O3(CMA) catalyst. The results indicate that the activity of partially sulphided CMA, produced by exposure to H2S or by hydrodesulphurization (h.d.s.) of ethanethiol

  噻吩与D 2的交换以及氘标记的丙烯和异丁烯的反应，然后结合质谱和微波光谱法，已用于表征商业CoO-MoO 3 -Al 2 O 3（CMA）的催化性质催化剂。结果表明，通过暴露于H 2 S或乙硫醇的加氢脱硫（hds）产生的部分硫化的CMA的活性与未负载的MoS 2的活性非常相似。因此，硫化CMA对噻吩中的α氢交换显示出高选择性/活性，并通过半氢化中间体催化丙烯中的双键迁移，这是MoS 2的活性特征，而氧化物CMA对α交换的活性低得多，并且对于后者反应显示路易斯酸型活性。似乎在hds期间CMA催化剂可以有用地描述为“双功能”，其中MoS 2负载在酸性载体上并由其稳定。

  olefinic C-H bonds with 2-aminophenylboranes. Computational and experimental studies reveal that the metal-free C-H insertion proceeds via a frustrated Lewis pair mechanism involving heterolytic splitting of the C-H bond by cooperative action of the amine and boryl groups. The adapted geometry of the reactive B and N centers results in an unprecedentently low kinetic barrier for both insertion into the

  CH 硼酸化是一种强大且原子效率高的方法，可将廉价且丰富的化学品转化为用于生产精细化学品和功能材料的多功能有机试剂。在此，我们报告了芳香族和烯烃 CH 键与 2-氨基苯基硼烷的简便 CH 硼酸化。计算和实验研究表明，不含金属的 CH 插入是通过受挫的路易斯对机制进行的，该机制涉及通过胺和硼基团的协同作用使 CH 键异裂。反应性 B 和 N 中心的适应性几何结构导致了前所未有的低动力学障碍，用于插入 sp(2)-CH 键和 sp(2)-CB 键在 2-氨基苯基(芳基)中的分子内质子化-或-（烯基）硼酸盐。这种常见的反应模式可作为各种催化反应的平台，例如 CH 硼化和炔烃的氢化。特别是，我们证明了简单的 2-氨基吡啶鎓盐可以有效地催化环戊二烯与儿茶酚硼烷的 CH 硼化。该反应可能是由与 2-氨基苯基硼烷等电子的硼物种介导的。
• Direct coupling of arenes and iodoarenes catalyzed by a rhodium complex with a strongly π-accepting phosphite ligand
  作者：Shuichi Yanagisawa、Tomoko Sudo、Ryoji Noyori、Kenichiro Itami

  A new rhodium-based catalytic system for the direct C-H coupling of arenes and iodoarenes that shows high activity with reasonably broad scope was developed. Under the catalytic influence of RhCl(CO)P[OCH(CF3)(2)](3)}(2) and Ag2CO3, the direct C-H arylation of heteroarenes and arenes took place with iodoarenes to afford a range of biaryls in good to excellent yields with high regioselectivity. Thiophenes, furans, pyrroles, indoles, and alkoxybenzenes are applicable to this arylation protocol. (C) 2008 Elsevier Ltd. All rights reserved.
• Microwave Spectra of Thiophene, 2‐ and 3‐Monodeutero, 3,3′‐Dideutero, and Tetradeuterothiophene. Structure of the Thiophene Molecule
  作者：Bo/rge Bak、Daniel Christensen、John Rastrup‐Andersen、Eileen Tannenbaum

  日期：1956.11

  2- and 3-monodeutero, 3,3′-dideutero, and tetradeuterothiophene have been prepared and their microwave spectra recorded together with the microwave spectrum of ordinary thiophene (C4H4S). Lines originating from the 4% content of C4H4S34 and the 2% content of C3C13H4S in ordinary thiophene (both the 2- and the 3-C13 species) were also identified. For all isotopic species rotational constants of high accuracy were obtained. The total material is sufficient for a complete determination of all the 8 geometrical parameters of thiophene.
