title: Aminosubstituted tert-butylsulfinylferrocenes as a new family of chiral ligands: asymmetric addition of diethylzinc to aldehydes.
abstract: A ready access to a new family of planar chiral ferrocenes, the (RFc,RS)-2-amino substituted 1-tert-butylsulfinylferrocenes, is described; in the case of the sulfonamide series enantioselectivities of up to 96% were obtained in the addition of Et2Zn to aromatic aldehydes.
