Redox Control of Light‐Induced Platinum‐Cluster‐to‐Iron Charge Transfer in a Bis(ferrocenylethynyl)‐Substituted Hexanuclear Platinum Derivative

Abstract

Give and take: Compound 1 (see structure: purple Pt, red Fe, green P, blue O; Fc=[(η-C5H5)Fe(η-C5H4)]) is prepared in good yields by the CuI-catalyzed coupling of two equivalents of ethynylferrocene with the hexanuclear cluster [Pt6(μ-PtBu2)4(CO)4Cl2]. Electrochemical and spectroelectrochemical data show the presence of photoelectrochemically triggered electron transfer from the {Pt6} core to the peripheral ferrocenyl subunits.
