C2-Symmetric 1, l',2,2'-tetrasubstituted ferrocene derivatives are prepared in high yields from chiral 1,1'-bis(oxazolinyl)ferrocenes v/a diastereoselective o,o'-dilithiation with sec-butyUithium followed by nucleophilic substitution. 1, l'-Bis(oxazolinyl)ferrocenes were prepared from 1,1 '-ferrocen
