Exchange reactions of copper complexes with amines
Square planar mixed ligand complexes of the type [CuLL′] where L = 5-chlorosalicylaldehyde and L′ = acetoacetanilide, have been synthesized on treatment with ammonia. Amine exchange of the above Schiff base complexes has been carried out on treatment with different amines. The reaction with ethanol amine is quite interesting compared to other amines. It reacts with 5-chlorosalicylaldehyde to form a Schiff base, while the β-diketone part is removed in the complex formation. All the complexes were characterized by elemental analysis, spectral studies, magnetic measurement, TLC, and conductane.
