Novel chiral N,O-ferrocenyl ligands, in which N and O groups were attached
to two different Cp rings of ferrocene, were synthesized from easily availa
ble ferrocene, and applied to the asymmetric diethylzinc addition to aldehy
des. High chemical yields and good enantioselectivities (up to 90.9% ee) we
re obtained by using ferrocene ligand 6. (C) 2000 Published by Elsevier Sci
