Outside Front Cover: Zwitterionic Acridinium Amidate: A Nitrogen‐Centered Radical Catalyst for Photoinduced Direct Hydrogen Atom Transfer

An organic zwitterion comprising an acridinium cation and an amidate anion directly linked by an N–N bond was developed by Takeshi Yanai, Olga García Mancheño, Kohsuke Ohmatsu, Takashi Ooi et al. in their Research Article (e202404890). With the aid of hexafluoroisopropanol as a pertinent hydrogen-bond donor, this zwitterion acts as a trifunctional photocatalyst to achieve efficient functionalization of inert aliphatic C–H bonds with electron-deficient olefins under blue-light irradiation by sequentially engaging in the hydrogen-atom transfer, single-electron reduction, and proton transfer.
