  在环境条件下，微小有机半导体在可见光促进下对 N-杂环进行高效有氧脱氢

  摘要：

  基于苝二酰亚胺 (PDI) 有机半导体开发了一种高效的可重复使用的催化系统，用于在可见光下对 N-杂环进行有氧脱氢。这种没有任何添加剂的实用催化体系在环境条件下进行。N-杂芳烃的微小聚集体被认为是天然产物、药物化学和材料科学中的特权结构。 [1] 因此，合成芳烃的温和方法的发展引起了有机合成化学家的兴趣[2]。将取代基选择性地引入 N-杂芳烃是一项艰巨的挑战，而对于相应的 N-杂环来说，这相对容易实现。例如，四氢喹啉可以很容易地进行 6 位亲电取代功能化，脱氢可得到相应的取代喹啉[3]。因此，N-杂环脱氢为N-杂芳烃被认为是一种可行的方法。与热促进的有机反应相比，利用可见光能作为有机转化的驱动力具有吸引力，因为它是一种温和、安全且易于处理的能源。 [4] 一般来说，N-杂环的可见光促进脱氢有两个亚类：无受体[2e,5]和受体辅助[3,6]，这取决于是否涉及氢受体。受体辅助脱氢，尤其是使用氧

  6-Nitro-1,2,3,4-四氢喹啉的合成：区域选择性硝化的实验和理论研究

  摘要：

  关于四氢喹啉硝化的文献的修订产生了许多不一致之处。因此，我们在实验和理论水平上对四氢喹啉及其几种 N 保护衍生物的硝化进行了深入研究。通常，硝化是在酸性条件下进行的，因此四氢喹啉会被 N-质子化；然而，如果氨基被保护，中性系统将是进行硝化的系统。已经探索了不同的保护基团，不仅有电子和空间效应，而且还有脱保护条件。此外，还研究了不同的试剂和反应条件。从这项研究中，我们已经能够在 6 位实现硝化的总区域选择性。已经进行了非常详细的 NMR 研究以明确表征四种硝基异构体。同时，进行了与实验结果一致的计算研究。为此，通过使用 B3LYP/6-31++G ** 级别的计算，所有四种硝基异构体的中性和 N 质子化的 σ​​ 配合物都在气相和水凝聚相中进行了优化。

  and stable core-shell catalysts. In this respect, we present the synthesis and characterization of iron oxides surrounded by nitrogen-doped-graphene shells immobilized on carbon support (labeled FeOx@NGr-C). Active catalytic materials are obtained in a simple, scalable and two-step method via pyrolysis of iron acetate and phenanthroline and subsequent selective leaching. The optimized FeOx@NGr-C catalyst

  纳米催化的一个重要目标是开发灵活有效的方法来制备活性稳定的核壳催化剂。在这方面，我们介绍了由固定在碳载体上的氮掺杂石墨烯壳包围的氧化铁的合成和表征（标记为 FeOx@NGr-C）。通过醋酸铁和菲咯啉的热解和随后的选择性浸出，以简单、可扩展的两步法获得活性催化材料。优化的 FeOx@NGr-C 催化剂在几种 N-杂环的氧化脱氢中表现出高活性。药学相关喹啉的合成证明了这种良性方法的效用。此外，机理研究证明反应通过超氧自由基阴离子（·O2(-)）进行。

  positive charge on the Co surface, thereby promoting the reaction. In contrast, cobalt nanocrystals supported by pristine carbon (Co NCs/C) proved to be inactive for oxidative dehydrogenation, owing to the lack of nitrogen. Moreover, in Co NCs/N-C, the N-doped graphitized carbon formed a protective layer for Co NCs, which preserved the active valence of Co species and prevented the catalyst from leaching.

  赋予非贵金属通常具有贵金属的高催化活性是替代贵金属的核心但具有挑战性的目标。为此，我们利用氮的配位效应，制备了氮掺杂石墨化碳稳定的钴纳米晶（Co NCs/NC）。所获得的Co NC/NC催化剂在极其温和的条件下对N-杂环的氧化脱氢及其逆加氢过程表现出非凡的性能。即使在室温（25℃）下，氧化脱氢也能实现近乎定量的转化，这归因于氮的配位效应：Co-N的相互作用在Co表面诱导部分正电荷，从而促进反应。相比之下，由于缺乏氮，由原始碳支撑的钴纳米晶体（Co NCs/C）被证明对于氧化脱氢没有活性。此外，在Co NCs/NC中，N掺杂的石墨化碳形成了Co NCs的保护层，保留了Co物种的活性价态并防止催化剂浸出。结果发现，催化剂经过5次再生循环后仍保持优异的催化活性；相比之下，其对应的氧化钴 (CoO x /NC) 几乎没有活性。至于其机制，电子顺磁共振（EPR）分析揭示了脱氢过程中超氧阴离子自由基的

In the presence of selected catalysts, rate accelerations of up to 2300 compared to virtually inactive reference compounds are observed. The catalyst loading can be reduced to 1 mol% while still achieving nearly full conversion for electron-poor and electron-rich quinolines. Contrary to expectations, preorganized catalysts
