ortho‐Quinones are underutilized six‐carbon‐atom building blocks. We herein describe an approach for controlling their reactivity with copper that gives rise to a catalytic aerobic cross‐coupling with phenols. The resulting aryl ethers are generated in high yield across a broad substrate scope under mild conditions. This method represents a unique example where the covalent modification of an ortho‐quinone
邻-喹诺酮是未充分利用的六碳原子构建基块。我们在本文中描述了一种控制其与铜的反应性的方法,该方法引起了与苯酚的催化好氧交叉偶联。在温和条件下,可在宽范围的底物范围内以高收率生成所得芳基醚。该方法代表了一个独特的例子,其中过渡金属催化了邻醌的共价修饰,为它们在合成中的利用创造了新的机会。
