The Cover shows a visible light‐induced benzylic C(sp 3 )−H photooxygenation driven by the co‐catalytic system of triplet‐excited DDQ and nitric oxides, which are generated in situ from tert ‐butyl nitrite and O 2 . In their Communication, F. Rusch et al. report that this photocatalytic protocol offers a dramatic increase of reaction rate relative to the thermal variant of the reaction, and a range of aromatic hydrocarbons and substituted indoles could be oxidized with good selectivity. Mechanistic control experiments suggest that benzylic cations are the key intermediates in the oxygenation reaction. More information can be found in the Communication by F. Rusch et al. on page 2881 in Issue 18, 2016 (DOI: 10.1002/cctc.201600704).
