  电化学双电子氧还原反应 (ORR) 诱导 α-重氮酯的有氧氧化

  摘要：

  电化学氧还原反应 (ORR) 是在合成化学中引入氧官能团的有力工具。然而，与成熟的单电子氧还原工艺相比，双电子氧还原在电化学合成中的应用研究较少。我们在此介绍了我们在通过双电子氧还原方法原位产生的过氧化氢将 α-重氮酯氧化为 α-酮酯方面的最新进展。在无外源氧化剂和无金属催化剂的电化学条件下，以中等至高产率获得了多种有价值的 α-酮酯产物。

  Synergistic use of electrochemistry and organometallic catalysis has emerged as a powerful tool for site-selective C-H functionalization, yet this type of transformation has thus far mainly been limited to arene C-H functionaliza-tion. Herein, we report the development of electrochemi-cal vinylic C-H functionalization of acrylic acids with al-kynes. In this reaction an iridium catalyst enables C-H/O-H

  可以通过三组分的连续活化-炔基化-环缩合（AACC）一锅法序列轻松合成2-取代的3-乙炔基喹喔啉生色团。与以前发表的从富电子的π-亲核试剂开始的四组分乙醛酸化作用相比，（杂）芳基乙醛酸的直接活化作用允许引入不能被乙醛化作用直接取代的取代基。通过引入N，N由于二甲基苯胺是2-位的强供体，因此3-乙炔基喹喔啉的发射溶剂变色性可以得到显着增强，以单个生色团在相对窄的极性窗口内覆盖从蓝绿色到深红色橙色的光谱范围。合成多组分反应概念的多样性导向性质使得可以通过Hammett相关性和Lippert-Mataga分析对结构-性质关系进行全面研究，并通过DFT阐明发射溶剂化变色π-共轭供体-受体系统的电子结构。具有PBEh1PBE功能的时间依赖性DFT计算可更好地再现最长波长吸收带的主要电荷转移特征。
