Chemistry. 2016 Dec 11. doi: 10.1002/chem.201605527. [Epub ahead of print]The compounds [Fe(CO)3(dRpf)]n+, n = 0,1,2 and dRpf = 1,1'-bis(dicyclohexylphosphino)ferrocene (n+) or 1,1' bis(diisopropylphosphino)ferrocene (n+), were obtained as two-step reversible redox systems by photolytic and redox reactions. The iron-iron distance decreases from about 4 Å to ca. 3 Å on oxidation, which takes place primarily at the tricarbonyliron moiety. Whereas ferrocene oxidation ... Read More
