  Rhodium-Catalyzed Direct Alkenylation and Arylation of Arene C−H Bonds via Decarbonylation of Cinnamoyl Chlorides, Cinnamic Anhydrides, and Poly(aroyl) Chlorides

  摘要：

  Efficient regioselective direct alkenylation of benzo[h]quinoline was realized with cinnamoyl chlorides as the coupling partners via decarbonylation of the chlorides and C-H bond activation by means of [Rh(CO)(2)Cl](2) as the catalyst in refluxing o-oxlene under phosphine-free conditions. For 2-phenylpridine, [Rh(CO)(2)Cl](2) or [Rh(COD)Cl](2) efficiently promoted its direct alkenylation with cinnamic anhydrides. Polyarenes were synthesized from [Rh(COD)Cl](2)-catalyzed decarbonylative poly(arylation) of isophthaloyl dichloride, terephthaloyl dichloride, or benzene-1,3,5,-tricarbonyl chloride with benzo[h] quinoline.

• The C–H activated controlled mono- and di-olefination of arenes in ionic liquids at room temperature
  作者：Kaifeng Du、Tian Yao

  DOI：10.1039/c9ra09736h

  日期：——

  In this study, controlled mono and di-olefination of arenes was first realized at room temperature via the C–H bond activation in ionic liquids, probably due to the positive effects of ionic liquids. It is an energy-saving routes in industrial production without the need for heating equipment. Different catalysts were screened, and it was found that [Ru(p-cymene)Cl2]2 generated mono-olefinated products

  在这项研究中，芳烃的受控单烯和双烯化首先在室温下通过离子液体中的C-H键活化实现，这可能是由于离子液体的积极作用。它是工业生产中无需加热设备的一条节能路线。筛选了不同的催化剂，发现[Ru( p-伞花烃)Cl 2 ] 2主要生成单烯化产物，而[Cp*RhCl 2 ] 2选择性生成二烯化产物。这些催化剂（[BMIM]NTf 2和[BMIM]PF 6）作为绿色且可回收的反应介质，在温和条件下具有高效性。该反应过程可以避免任何挥发性和对环境有毒的有机溶剂，并且不需要密闭设备，更加安全。实现了宽底物范围、良好的产率和令人满意的选择性。该反应可以放大至克级。此外，昂贵的铑/钌催化体系可循环使用至少6次，且始终保持较高的催化活性，从工业角度来看是经济且环保的。根据机理研究，C-H键断裂可能是通过协同金属化-去质子化来实现的。该技术可用于多种有价值的不饱和芳香族化合物的合成，显示出巨大的工业化生产潜力。

  elimination. Two types of catalytically relevant species were identified, and the reactivities of these species, combined with the results of the kinetic studies, suggest that the rate-limiting step is the exchange of the COD ligand with the alkenyl ester. On the basis of the elucidated mechanism, the first catalytic coupling reaction using aromatic C–H bonds with C–O bonds of ethers was also developed

  使用Ru（cod）（cot）作为催化剂，开发了芳基吡啶基和杂芳基吡啶及相关化合物的芳香族C–H键与烯基酯的直接，区域选择性烯基化反应。使带有电子多样性取代基和各种杂环定向基团的芳族化合物与带有带有脂族和芳族取代基的单和二取代烯基的乙酸烯基酯反应，以高收率得到邻烯基化产物。使用不同比例的E和Z进行氘标记实验和竞争反应的结果β-苯乙烯基乙酸酯的异构体表明，C–H烯基化反应是通过钌–烯烃中间体进行的，乙酸烯基酯的C–O键被β-乙酰氧基消除而裂解。确定了两种类型的催化相关物种，这些物种的反应性与动力学研究的结果相结合，表明限速步骤是COD配体与烯基酯的交换。在阐明机理的基础上，还开发了第一个使用芳族C–H键与醚的C–O键的催化偶联反应。

  catalyzed by group 9 Cp*M(III) complexes. By using Cp*Rh(III)-catalyzed isocoumarin synthesis as a model reaction, experimental and theoretical mechanistic studies were conducted. The results concluded that the Rh(III)–Rh(I)–Rh(III) rather than the Rh(III)–Rh(V)–Rh(III) pathway is more likely involved in the mechanism, and both the C–H activation and oxidation of the Cp*Rh(I) species were involved in

  第9组Cp * M（III）（M = Co，Rh，Ir）配合物已被广泛研究用作各种C–H活化反应的催化剂。通常，在这些催化体系中使用后期金属基银盐或铜盐作为氧化剂（需要时）。在此，我们报告了一种潜在的通用类型的含N–O键的氧化剂的发现，该氧化剂可通过9 Cp * M（III ）复合体。通过使用Cp * Rh（III）催化的异香豆素合成作为模型反应，进行了实验和理论机理研究。结果表明，Rh（III）–Rh（I）–Rh（III）途径更可能参与了该机理，而不是Rh（III）–Rh（V）–Rh（III）途径，
