We describe a photocatalytic system that reveals latent photooxidant behavior from one of the most reducing conventional photoredox catalysts, N-phenylphenothiazine (PTH). This aerobic photochemical reaction engages difficult to oxidize feedstocks, such as benzene, in C(sp2)–N coupling reactions through direct oxidation. Mechanistic studies are consistent with activation of PTH via photooxidation and
我们描述了一种光催化系统,该系统揭示了最具还原性的传统光氧化还原催化剂之一N-苯基吩噻嗪 ( PTH ) 的潜在光氧化行为。这种有氧光化学反应通过直接氧化在 C(sp 2 )-N 偶联反应中参与难以氧化的原料,如苯。机理研究与通过光氧化激活PTH和路易斯酸助催化剂清除在该过程中不可避免地形成的抑制剂一致。
