摘要：

The kinetics of the electron transfer between reduced spinach [2Fe‐2S]‐ferredoxin and the optically active complexes [Co((R,R)‐ or (S,S)‐alamp)py]+ (I), [Co((R,R)‐ or (S,S)‐promp)H2O]+ (IIa), and [Co((R,R)‐ or (S,S)‐promp)py]+ (IIb) have been investigated. The reactions are stereoselective, and for I and IIa, the Stereoselectivity strongly depends on temperature due to large differences in the activation enthalpy between enantiomeric reagents. Isokinetic behaviour is observed between enantiomers, the ΔΔH Δ–Λ# values being largely compensated by the ΔΔS Δ–Λ# values. The compensation behaviour is explained by the combination of stereochemical interactions and desolvation processes on formation of the precursor complex or the transition state.
