Back Cover: Boron‐Centered Lewis Superacid Through Redox‐Active Ligands: Application in C−F and S−F Bond Activation (angew. Chem. Int. Ed. 13/2023)

One-electron oxidation converts the ferrocene-substituted borane into a Lewis superacid, as reported by Frank Breher, Jan Paradies, and co-workers in their Communication (e202216959). The Lewis superacid activates almost inert carbon–fluorine and sulfur–fluorine bonds for reductions, alkylations, and arylations to form new chemical bonds.
