Correspondence on “Water‐Derived Radical Species Initiate Six‐Electron Oxidation of Cyclic Ketones in Microdroplets” Angew. Chem. Int. Ed . 2026, e1888676

Cooks and coworkers ( Angewandte Chemie 65 (2026), e1888676, https://doi.org/10.1002/anie.1888676 ) claim that cyclic ketones are oxidized by H 2 O •+ . Formation of this species requires a substantial input of energy to be formed and is, even if it were to be formed, too short‐lived to participate in bimolecular reactions.
