文摘
The chiral diamine (S,S)-bis(2,5-dimethylpyrrolidinyl)ferrocene (6) was prepared from diaminoferrocene and (2R,5R)-2,5-hexanediol cyclic sulfate in thepresence of a base. The short C-N bond, long Fe-C(N)bond, and planar nitrogen observed in the crystal structure of 6 are consistent with efficient N-to-Cp electrondonation. The resulting electron-rich metal center (withthe most negative shift in redox potential yet observed foraminoferrocenes) was characterized electrochemically.
