Aromatization as the driving force for single electron transfer towards C–C cross-coupling reactions
There is a strong current interest in C–H functionalization reactions under metal-free conditions. We report herein the deprotonated form of dihydrophenazine (DPh) as a potent initiator under photochemical conditions that can efficiently generate aryl radicals via singleelectrontransfer (SET). The driving force for such electrontransfer is the gain in aromaticity for the initiator molecule. Using
目前对无金属条件下的 C-H 官能化反应有着浓厚的兴趣。我们在此报告了去质子化形式的二氢吩嗪 (DPh) 作为光化学条件下的有效引发剂,可以通过以下途径有效地产生芳基自由基单电子转移(SET)。这种电子转移的驱动力是引发剂分子芳香性的增加。使用这种方法,一系列芳烃和杂芳烃在室温下与芳基交叉偶联。Stern-Volmer 动力学分析证明了 DPh 阴离子的光化学活化和随后的电子转移至底物芳基重氮盐。包括拦截重要反应中间体在内的详细机理研究证明,芳香性驱动的 SET 是生成芳基自由基对自由基促进的交叉偶联反应的关键步骤。

Manganese photocatalysts enabled versatile room‐temperatureC−H arylation reactions by means of continuous visible‐light photoflow, thus allowing for efficient C−H arylations in 30 minutes with ample scope. The robustness of the manganese‐catalyzed photoflow strategy was shown by visiblelight‐induced gram‐scale synthesis, clearly outperforming the batch performance.
