摘要：

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 H-1 NMR measurements of copper(II) or nickel(II) complexes as well as copper(II)-extraction experiments. Intramolecular interactions between pi electrons of the benzyl group and the metal centre of the complex are proposed to occur.
