Strong as an Ox: A dicationic compound with a 9,10‐dihydroanthracene skeleton has been produced from the corresponding 9,10‐dialkoxy‐9,10‐dihydroanthracene, which was readily prepared from anthraquinone. The dication functions as a powerful two‐electronoxidant, comparable to aminium cation radicals, and has been employed in oxidative processes such as the self‐coupling of anilines and naphthols, and

Two different reaction pathways in the photooxygenation of 9,10-diarylanthracenes are identified, with strong evidence for polar (forward, singlet oxygen addition) and radical (backward, thermolysis) intermediates.
