A merger of a metal‐free [2+2] cycloaddition and an S‐centered radical induced 1,4‐addition of benzene‐linked allene‐ynes has been established. In their Communication on page 15570 ff., B. Jiang et al. describe the utility of their reaction for accessing functionalized cyclobuta[ a ]naphthalen‐4‐ols. The picture shows the eagles bringing together the components of the reaction.
