Figure 3. Summary of reactions observed for [1]2+ with CO and H2.

Figure 3

Compound numbering and relevant oxidation states are shown, using italics for the ferrocenyl iron centre. The starting compound 1 is in a fully reduced state. Initial oxidation of 1 is localized on the diiron core as shown by FT-IR and EPR measurements. The second oxidation (to [1]2+) converts the FcP* centre from ferrous to ferric. Reactions of [1]2+ with H2 and with CO involve substrate binding coupled to intramolecular electron-transfer (ET) from the diiron subunit to the oxidized FcP* ligand.
