Some metal-ion complexes with ligands formed by reaction of amines with aliphatic carbonyl compounds. Part II. Some nickel(II) and copper(II) compounds formed by the 1,2-diaminopropane–acetone reaction

Abstract

Reaction of bis(1,2-diaminopropane)nickel(II) with acetone yields the bis-complex of the β-amino-ketone NH2·CH(CH3)·CH2·NH·C(CH3)2·CH2·CO·CH3 which acts as a tridentate ligand. In pyridine this is converted into the nickel(II) complex of the macrocyclic ligand C-meso-3,5,7,7,10,12,14,14-octamethyl-1,4,8,11-tetra-azacyclotetradeca-4,11-diene, L. The bis(R-1,2-diaminopropane) complex reacts to form an analogous β-amino-ketone complex which in pyridine yields the RR-enantiomorph of the nickel(II) complex of C-rac-L. The tris(1,2-diaminopropane)nickel(II) and copper(II) complexes react with acetone to yield a mixture of two products. These are C-meso- and C-rac-[M(L)]2+ for nickel(II), and probably also for copper(II).
