Thermal Intramolecular Electron Transfer in a Ferrocene-Naphthoquinone Linked Dyad Promoted by Metal Ions

Abstract

Initiated by metal ions: Intramolecular electron transfer in a donor–acceptor linked system (a ferrocene–naphthoquinone dyad Fc–NQ; see scheme) can be started thermally by adding an appropriate metal ion (Sc3+) which can promote thermal electron transfer, which would otherwise be unlikely to occur, to give a radical ion complex (Fc+–NQ.−/Sc3+).
