  electrophotocatalytic oxidation platform. This chemistry employs a trisaminocyclopropenium (TAC) ion catalyst, which is electrochemically oxidized to form a cyclopropenium radical dication intermediate. The radical dication undergoes photoexcitation with visible light to produce an excited-state species with oxidizing power (3.33 V vs. SCE) sufficient to oxidize benzene and halogenated benzenes via single-electron

  可见光光催化和电催化是促进化学反应的两种强大策略。在这里，这两种模式结合在电光催化氧化平台中。该化学过程采用三氨基环丙烯 (TAC) 离子催化剂，通过电化学氧化形成环丙烯自由基阳离子中间体。自由基阳离子在可见光下进行光激发，产生具有氧化能力（3.33 V vs. SCE）的激发态物质，足以通过单电子转移（SET）氧化苯和卤代苯，从而导致 CH/NH 与唑类偶联。提供了光激发物质的强氧化行为的基本原理，同时通过顺式2,6-二甲基哌啶部分的特定构象合理化了催化剂的稳定性。

  An efficient copper-catalyzed arylation reaction of 1-acyl-1H-1,2,3-benzotriazoles with diaryliodonium salts via C–N activation is explored. The reaction is conducted regioselectively to form 1-aryl-1H-1,2,3-benzotriazoles in MeCN at 80 °C in the presence of cesium carbonate. 29 examples are given with the product yield of up to 84%. The probable reaction mechanism is proposed.
