Boron‐Centered Lewis Superacid through Redox‐Active Ligands: Application in C−F and S−F Bond Activation

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 superacid activates almost inert carbon–fluorine sulfur–fluorine bonds for reductions, alkylations, arylations to form new chemical bonds.
