Some metal-ion complexes with ligands formed by reaction of amines with aliphatic carbonyl compounds. Part V. Nickel(II)β-hydroxyimine complexes formed by reaction of amine complexes with 4-hydroxy-4-methylpentan-2-one

Abstract

Bis complexes of nickel(II) with ethylenediamine, propane-1,2- and 1,3-diamine, iso, meso, and probably rac-dimethylethylenediamine, 1,2-diphenylethylenediamine, and o-phenylenediamine, and mono complexes of 4-azaheptane-1,7-diamine and 3,6-diazaoctane-1,8-diamine react with 4-hydroxy-4-methylpentan-2-one (hmp)(diacetone alcohol) over a period of hours at room temperature to yield complexes of β-hydroxyimines. The hydroxy-groups are co-ordinated to give tridentate (diamines) or quinquedentate ligands (4-azaheptane-1,7-diamine with two β-hydroxyimino-groups, and 3,6-diazaoctane-1,8-diamine with one). The complexes are hydrolysed, more or less rapidly, to reform the amine complex and hmp. Nickel(II) complexes of several other triamines and tetra-amines, and copper(II) complexes with several amines, do not react with hmp under the same conditions.
