  氧化还原储电极实现水性和非水性电合成反应的配对

  摘要：

  配对电解方法对于化学合成很有吸引力，因为它们在两个电极上都能产生有价值的产物。然而，由于两个半反应需要在相互兼容的条件下进行，因此此类反应的发展变得复杂。在这里，模块化电化学合成（ModES）策略使用“氧化还原库”（RR）来配对水性和非水性溶剂中的电化学半反应，从而绕过了这些限制。使用六氰基铁酸镍将有机溶剂中的电化学氧化反应、4-叔丁基甲苯在甲醇中转化为苄基二甲缩醛和醛或萘在乙腈中的氧化C-H胺化反应以及水中氧还原成过氧化氢反应进行配对作为 RR，可以选择性地存储和释放质子（和电子），同时充当这些反应的对电极。通过 RR 的选择性质子传输经过优化和确认，可实现离子平衡，从而实现以不同速率、不同规模、在不同溶剂（甲醇、乙腈和水）中进行的氧化还原半反应之间的成功配对。

  report the photocatalytic C–H amination of aromatics overcoming redox potential limitations. Radical cations of aromatic compounds are generated photocatalytically using Ru(phen)3(PF6)2, which has a reduction potential at a high oxidation state (Ered(RuIII/RuII) = +1.37 V vs SCE) lower than the oxidation potentials of aromatic substrates (Eox = +1.65 to +2.27 V vs SCE). The radical cations are trapped
