Some Metal-Ion Complexes with Ligands Formed by Reactions of Amines with Aliphatic Carbonyl Compounds. VII. Copper(II) Compounds of Some β-Imino Amines, Formed by Reaction of Copper(II) Chelate Amine Complexes with 4-Amino-4-methylpentan-2-one

Compounds of copper(II) with chelated β-imino amines are formed by reaction between 4-amino-4-methylpentan-Zone (amp) and copper(II) complexes of ethane-1,2-diamine, propane-1,2- and -1,3-diamine, meso-l,2-diphenylethane-l,2-diamine, 2-(2-aminoethyl)pyridine, 3-azapentane-1,5-diamine, 3-azahexane-1,6-diamine, 4-azaheptane-1,7-diamine, 3,6-diazaoctane-1,8-diamine, 4,8-diazaundecane-1,11-diamine, 3-(2-aminoethyl)-3-azapentane-1,5-diamine and 4,6,6-trimethyl-3,7-diazanon-3-ene-1,9-diamine. Compounds with one β-imino amine group were formed for all the amines, except 1,2-diphenylethane-1,2-diamine and propane-1,3-diamine, and compounds with tetradentate ligands with two β-imino amine groups were formed with the aliphatic diamines. The imine group of the compounds is relatively resistant to hydrolysis.
