Organometallic Fe?Fe Interactions: Beyond Common Metal?Metal Bonds and Inverse Mixed-Valent Charge Transfer
The compounds [Fe(CO)3(dRpf)]n+, n=0, 1, 2 and dRpf=1,1?-bis(dicyclohexylphosphino)ferrocene ([1]n+) or 1,1?-bis(diisopropylphosphino)ferrocene ([2]n+), were obtained as two-step reversible redox systems by photolytic and redox reactions. The iron?iron distance decreases from about 4 A to about 3 A on oxidation, which takes place primarily at the tricarbonyliron moiety. Whereas ferrocene oxidation is calculated to occur only in excited states, the near infrared absorptions of the mixed-valent monocations are due to an unprecedented ?inverse? inter-valence charge transfer from the electron-rich iron(II) in the ferrocene backbone to the electron-deficient tricarbonyliron(I). Protonation of complex 1 results in the formation of the structurally characterized hydride [1H]BF4, which reacts with acetone to form the dication, 12+, and isopropanol. While the hydride [2H]BF4was found to be unstable, protonation of 2 in acetone resulted in the clean formation of 22+,formally a hydrogen transfer.
