Ferrocenes, which are typically air‐stable outer‐sphere single‐electron transfer reagents, were found to react with dioxygen in the presence of B(C 6 F 5 ) 3 , a Lewis acid unreactive to O 2 , to generate bis(borane) peroxide. Although several Group 13 peroxides have been reported, boron‐supported peroxides are rare, with no structurally characterized examples of the BO 2 B moiety. The synthesis of a bis(borane)‐supported peroxide anion and its structural and electrochemical characterization are described.
