N-Phenyl-3-oxo-butanamide, (1), which is used in dyes and pigment synthesis, on reaction with hydroxylamine gives N-phenyl-3-hydroxyimino-butanamide (2). This compound reacts with diazonium salts to give diazo products which coordinate to copper(II) and iron(III). The intermediate obtained from the preparation of the ligand, the ligand itself and the metal complexes were characterised by magnetic susceptibility, spectroscopic techniques such as IR, ¹H NMR, UV-Vis. and microanalytical data.
