Unlocking a Ferrocenium Superoxidizer with the Perfluorinated Cp* Ligand.

ABSTRACT: The photolytically induced arene displacement of [Fe(C₅H₅)(oDCB)][PF₆] (oDCB = ortho-dichlorobenzene) in the presence of [NEt₄][C₅(CF₃)₅] afforded the highly fluorinated and benchstable ferrocene [Fe(C₅H₅)(C₅(CF₃)₅)]. The perfluorinated Cp* ligand exerts an extreme electron withdrawing effect on the ferrocene with E_1/2 = 1.35 V (versus Fc/Fc⁺). This proved to be the highest value obtained for any ferrocene reported so far. The corresponding stable and storable ferrocenium complex [Fe(C₅H₅)(C₅(CF₃)₅)][AsF₆] was generated in quantitative yield and represents not only the most
