It has been found that substituents on N,N'-bis (8-quinolyl)malonamide play an important role in copper(II) extraction: among the substituents studied, benzyl groups dramatically increased extractability of the malonamide complex.The role of substituents is discussed on the basis of the results of titration and 1H NMR measurements of copper(II) or nickel(II) complexes as well as copper(II)-extraction experiments.Intramolecular interactions between ? electrons of the benzyl group and the metal centre of the complex are proposed to occur.
