  N-Acyloxyphthalimides as Nitrogen Radical Precursors in the Visible Light Photocatalyzed Room Temperature C–H Amination of Arenes and Heteroarenes

  摘要：

  This paper reports a room temperature visible light photocatalyzed method for the C-H amination of arenes and heteroarenes. A key enabling advance in this work is the design of N-acyloxyphthalimides as precursors to nitrogen-based radical intermediates for these transformations. A broad substrate scope is presented, including the selective meta-amination of pyridine derivatives. A radical aromatic substitution mechanism is proposed.

  Two-for-one approach to photoredox In photoredox catalysis, an excited chromophore typically activates a single reactant either by oxidizing or reducing it. Ghosh et al. used a semiconductor catalyst to activate two reactants at once by quenching both an excited electron and the residual positive hole (see the Perspective by Swift). As such, two different reactive carbon or halide fragments could be

  光氧化还原二合一方法 在光氧化还原催化中，激发的发色团通常通过氧化或还原单个反应物来激活它。戈什等人。使用半导体催化剂通过淬灭激发的电子和残留的空穴来同时激活两种反应物（参见 Swift 的观点）。因此，可以将两个不同的反应性碳或卤化物片段附加到芳环上的不同位点。该催化剂还可以耐受氰化物等强亲核试剂，并且可以轻松回收和重复使用。科学，这个问题 p。360; 另见第。320 半导体光催化剂上氧化和还原位点的形成促进了双自由基加成反应。半导体表面上的光激发电子-空穴对可以与两种不同的基材进行氧化还原反应。与传统的电合成类似，主要的氧化还原中间体仅提供单独的氧化和还原产物，或者更罕见地结合成一种加成产物。在这里，我们报告了一种稳定的有机半导体材料，介孔石墨碳氮化物 (mpg-CN)，可以充当可见光光氧化还原催化剂，以协调氧化和还原界面电子转移到两个或三个组件中的两种不同基材。用于芳烃和杂芳烃的直接双重碳氢功能化的系统。mpg-CN

  A phosphonium ylide-based visible light organophotoredox catalyst has been designed and successfully applied to halohydrin synthesis using trichloroacetonitrile and epoxides. An oxidative quenching cycle by the ylide catalyst was established, which was confirmed by experimental mechanistic studies.

Structurally diverse aromatic imides were obtained in moderate to good yields.

• <i>N</i>-Aminopyridinium Salts as Precursors for N-Centered Radicals – Direct Amidation of Arenes and Heteroarenes
  作者：Tobias W. Greulich、Constantin G. Daniliuc、Armido Studer

  Readily prepared N-aminopyridinium salts are valuable precursors for the generation of N-centered radicals. Reduction of these salts by single electron transfer allows for clean generation of amidyl radicals. It is shown that direct radical C-H amination of heteroarenes and arenes can be achieved with N-aminopyridinium salts under mild conditions by using photoredox catalysis.
