Δr>23.5kcal/molES/EChemPugh and Meyer, 1988solvent: Acetonitrile; The lower limit is the reaction Gibbs energy
Δr23.kcal/molKinSCutler and Rosenblum, 1976solvent: Benzene; The reaction enthalpy was derived from the activation enthalpy of the disproportionation reaction [Fe(Cp)(C5H4COMe)(CO)2]2(solution) = 0.5[Fe(Cp)(CO)2]2(solution) + 0.5[Fe(C5H5COMe)(CO)2]2(solution), 26.9 ± 2.7 kcal/mol, whose rate-determining step corresponds to Fe-Fe cleavage after isomerization of the complex with two bridging carbonyls to a "linear" (no bridging carbonyls) structure Cutler and Rosenblum, 1976. The enthalpy of this isomerization was estimated as 4.1 kcal/mol Cutler and Rosenblum, 1976
