  利用二氧化铜作为可循环催化剂，由吲哚啉/二氢吲哚羧酸经芳构化然后进行C–N交叉偶联反应，可有效合成N-取代的吲哚

  摘要：

  通过将二氢吲哚/二氢吲哚羧酸芳构化，然后在作为可回收催化剂的纳米CuO Cs 2 CO 3的存在下，与各种芳基卤化物进行C–N交叉偶联，开发了一种新的且优雅的合成1-取代的吲哚的方案。在80°C下用作DMSO的碱。得到的1-取代的吲哚的收率高至优异，催化体系最多可循环使用四个循环而不会损失催化活性。

• Scope, Kinetics, and Mechanism of “On Water” Cu Catalysis in the C-N Cross-Coupling Reactions of Indole Derivatives

  Cu(I)/phenanthroline catalyzed C–N cross coupling reactions of indole derivatives in the aqueous and DME/H2O solvent systems are faster than the reactions performed in organic solvents (DME). Theoretical calculations show that water can induce rate acceleration by stabilizing the transition state of the rate‐determining oxidative addition step through hydrogen‐bonding interactions.

  在水性和DME / H 2 O溶剂体系中，Cu（I）/菲咯啉催化的吲哚衍生物的C–N交叉偶联反应比在有机溶剂（DME）中进行的反应更快。理论计算表明，水可以通过氢键相互作用来稳定决定速率的氧化加成步骤的过渡态，从而诱导速率加速。

  Well faceted CuO nanoparticles were synthesized by thermal-assisted green strategy at reflux temperature in a short period of time. A possible growth mechanism of such highly faceted nanostructures based on typical biomolecule-crystal interactions in aqueous solution is tentatively proposed. The large surface area (223.36 m(2)/g) and rich exposed active sites are expected to endow such nanostructures with excellent performances in catalysis as demonstrated here for remarkable catalytic activity with respect to the N-arylation of indoles. Nanoparticles were characterized by X-ray diffraction, scanning electron microscopy and transmission electron microscopy. Both the activity and selectivity of the N-arylation reactions could be tuned by varying the concentration of CuO nanoparticles. Nanoparticles catalyst were recycled and reused for further catalytic reactions with minimal loss in activity. A variety of indole derivatives afforded corresponding N-arylation product with excellent yields (up to 98%). (C) 2012 Elsevier B.V. All rights reserved.
