Sonochemical Synthesis of Cobalt‐Oxo‐Cubanes as Redox‐Active Platform for Proton‐Coupled Electron Transfer

Chemistry – A European Journal, EarlyView.
A facile sonochemical method for rapid and gram‐scale synthesis of ligand‐tunable cobalt‐oxo‐cubanes is reported. Electrochemical studies reveal a Co4O4‐centered one‐electron oxidation and PCET pathway, while identifying Co2+ impurities as key disruptors of true cubane redox chemistry.
