The complex [CpFe(dppf)(CO)][B(ArF)4] [1][B(ArF)4] (Cp = cyclopentadienyl, dppf = 1,1′-bis(diphenylphosphino)ferrocene, and [B(ArF)4]−= tetrakis[3,5-bis(trifluoromethyl)phenyl]borate) was made by removal of one carbonyl ligand from the dicarbonyl complex [CpFe(CO)2(κ1-dppf)]I and exchange of the I–for [B(ArF)4]−that allowed for electrochemical investigations. The cyclic voltammogram of [1]+showed a reversible anodic process due to oxidation of the ferrocenediyl moiety of the dppf ligand. A quasi-reversible cathodic process was also observed, and this reduction occurred at the CpFe moiety, as determined by variable-temperature (+22 and −30 °C) IR spectroelectrochemistry (SEC) and further supported by DFT calculations. This reduction event resulted in the formation of the two possible dimers [Cp2Fe2(μ-CO)2(μ-dppf)] and [Cp2Fe2(CO)2(μ-dppf)] along with deligation of one dppf ligand. |
