Novel Unsymmetric Chiral Schiff Bases Possessing Two Different Donor Moieties: Unique Tetradentate Ligands from Combination of Salicylaldehyde and Acetylacetone Units.

Abstract A new class of novel chiral Schiff base ligands has been developed using a stepwise approach. The key feature of these new ligands is that they possess two different donor units, one of them is aromatic while the other is non-aromatic.
