pyridine-3-carboxamide derivatives
benzamide derivatives - Opis:
- The extraction studies for copper(II) from chloride solutions by mono- and dialkyl derivatives of benzamide and pyridine-3-carboxamide show that the coordination of copper by amide groups is very weak, weaker than by chloride ions. N,N-dialkyl derivative of benzamide does not extract copper from chloride media but N-alkylbenzamide eliminates a small amount of copper (a great deal smaller than pyridine-3-carboxamide derivatives) only from diluted chloride aqueous solutions ([Cl-] < 0.1 M). Infrared studies of copper complexes with mono- and dialkylpyridine-3-carboxamides show that coordination of the ligand molecules to copper(II) ions takes place mainly by the pyridine nitrogen. More stable monoalkylpyridinecarboxamides complexes with CuCl2 are formed probably by intermolecular hydrogen bonds between monomeric molecules of CuCl2L2 complex (L – the amide). However, weak coordination of copper(II) by the amide group may take place.
