A combination of ruthenium and photoredox catalysis allowed the ortho olefination of phenols. Using visible light, the direct C-H functionalization of o-(2-pyridyl)phenols occurred, and diverse phenol ethers were obtained in good yields. The regeneration of the ruthenium catalyst was accomplished by a photoredox-catalyzed oxidative process.
钌和光氧化还原催化的组合允许苯酚的邻位烯烃化。使用可见光，发生了邻-(2-吡啶基)苯酚的直接 C-H 官能化，并且以良好的收率获得了各种苯酚醚。通过光氧化还原催化的氧化过程完成了钌催化剂的再生。
