Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The importance of aromatic CO, CN, and CS bonds necessitates increasingly efficient strategies for their formation. Herein, we report a biomimetic approach that converts phenolic CH bonds into CO, CN, and CS bonds at the sole expense of reducing dioxygen (O₂) to water (H₂O). Our method hinges on a regio‐ and chemoselective copper‐catalyzed aerobic oxygenation to provide <italic>ortho</italic>‐quinones. <italic>ortho</italic>‐Quinones are versatile intermediates, whose direct catalytic aerobic synthesis from phenols enables a mild and efficient means of synthesizing polyfunctional aromatic rings.</p> </abstract>
