  吲哚与 Oxone-卤化物的绿色卤化

  摘要：

  吲哚的氧化官能化是开发吲哚合成效用的最广泛使用的方法之一。为了延续我们对吲哚绿色氧化的研究兴趣，我们进一步探索了吲哚与过氧化氢卤化物的氧化，发现吲哚氮上的保护基团在控制吲哚与过氧化氢卤化物氧化的途径中起着决定性作用。吲哚氮上的吸电子基团（N-EWG）可以用化学计量的卤化物进行C2卤化，而使用化学计量的卤化物可以选择性地实现C3卤化，而不依赖于吲哚氮上保护基团的电子性质。与我们之前使用催化卤化物获得的结果不同，这些发现导致开发出一种环境友好、高效且温和的方案来获取 2- 或 3- 卤代吲哚（氯代和溴代）。与之前的2-/3-卤代吲哚的合成方法相比，我们的方法利用过氧化氢卤化物中原位产生的反应性卤化物质来卤化吲哚，从而消除了化学计量卤化剂的使用以及有毒有害物质的产生。源自氧化剂的有机副产品。

  Upon light-induced isomerization, diarylethenes (DAEs) equipped with reactive aldehyde moieties rearrange selectively in the presence of amines, accompanied by decoloration. In a comprehensive study, the probe structure was optimized with regard to its inherent reactivity in the nucleophile-triggered rearrangement reaction. Detailed structure-reactivity relationships could be derived, in particular

  在光诱导异构化后，带有反应性醛部分的二芳基乙烯 (DAE) 在胺存在下选择性地重排，并伴有脱色。在一项综合研究中，探针结构根据其在亲核试剂触发的重排反应中的固有反应性进行了优化。可以推导出详细的结构-反应关系，特别是关于整合（杂）芳基部分的类型以及甲酰基残基的位置，并且优化了探针与伯胺和仲胺的固有反应性。利用辅助碱基，最初形成的重排产物可以参与随后的催化循环，导致放大的脱色过程。这种额外的催化途径使我们能够提高我们方法的灵敏度并成功区分胺和硫醇。此外，已设计出表现出强分析物诱导荧光调制的探针，以通过使用更灵敏的读数进一步降低检测限。优化的 DAE 探针是未来可编程传感材料和设备的有前途的分子组件。

  palladium-catalyzed processes. The zirconaaziridine-mediated palladium (ZAPd)-catalyzed reaction shows excellent compatibility with various functional groups and diverse heteroaromatic scaffolds. In accord with density functional theory (DFT) calculations, a redox transmetallation between the oxidative addition product and the zirconaaziridine is proposed as the crucial elementary step. Thus, cross-coupling selectivity

  过渡金属催化的交叉亲电偶联 (XEC) 是锻造 C(sp 2 )–C(sp 2 ) 的有力工具) 联芳基分子中来自丰富芳族卤化物的键。虽然通过多金属 XEC 合成不对称联芳基化合物具有很高的合成价值，但两种杂芳族卤化物的选择性 XEC 仍然难以捉摸且具有挑战性。在这里，我们报告了一种均相 XEC 方法，该方法依赖于锆氮丙啶配合物作为双钯催化过程的穿梭。锆氮丙啶介导的钯 (ZAPd) 催化反应显示出与各种官能团和各种杂芳族支架的良好相容性。根据密度泛函理论 (DFT) 计算，氧化加成产物和锆氮丙啶之间的氧化还原金属转移被认为是关键的基本步骤。因此，使用单一过渡金属催化剂的交叉偶联选择性由 Pd(0) 氧化加成到芳族卤化物的相对速率控制。总体而言，组合还原剂和金属转移剂的概念为过渡金属还原偶联催化的发展提供了机会。
