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
Lewis acid catalyzed allylation of 1,2-naphthoquinones and o-benzoquinones with allyltributyltins gave monoallylation products in reasonable to high yields.
