Abstrakt: The chiral diamine (S,S)-bis(2,5-dimethylpyrrolidinyl)ferrocene (6) was prepared from diaminoferrocene and (2R,5R)-2,5-hexanediol cyclic sulfate in the presence 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 electron donation. The resulting electron-rich metal center (with the most negative shift in redox potential yet observed for aminoferrocenes) was characterized electrochemically.
