Abstract
Abstract Nitration of the coordinated ligands in the complexes bis[1-(2-hydroxyphenyl)ethylideneamine or its methyl derivative]Cu(II) and N,N′-ethylene or propylene bis[1-(2-hydroxyphenyl)ethylideneaminato]Cu(II) have been carried out. Similar nitration reactions of mixed diamine Schiff base complexes of Cu(II) have also been carried out. The substitution products have been characterized by elemental analyses, comparison with authentic samples in case of binary complexes and by means of magnetic moments, electronic and IR spectral studies. The orientation of incoming substituents in the chelates is found to be the same as that in uncomplexed 2-hydroxyacetophenone or methyl substituted 2-hydroxyacetophenone. Nitration reactions in case of mixed ligand complexes confirm the structure.
