The Schiff bases – salicylaldehyde, o-hydroxyacetophenone, acetylacetone, or benzoylacetone- are a class of mono-negative NNO donor ligands that quickly react with transition metal ions, particularly Cu(II). They are produced by mono-condensing diamines with carbonyl compounds. These ligands are widely used and easily accessible. They display different denticities and functionalities depending on the nature of the starting materials (primary amines and carbonyl precursors). The ligand enables effective control over the stereochemistry of the metallic centres in homo and hetero polynuclear complexes, depending on the quantity, type, and relative location of the donor atoms of a Schiff base. Schiff bases are excellent ligands for the synthesis of metal complexes relevant to bioinorganic chemistry, catalysis, encapsulation, transport, and separation processes because of all these benefits.
