Salen-type Schiff base ligands incorporating two different benzylidene moieties and a diamine backbone were synthesized in high yield (80-90%) under mild conditions via a stepwise approach. In the first step, anhydrous hydrochloric acid was used to selectively protect one amino group of the vicinal
Condensation of the O-protected planar chiral hydroxyferrocene carbaldehyde (S p )-1 with ethylenediamine, followed by deprotection gave rise to the "ferro-salen" ligand (S p ,S p )-3 in good yield.
