Stereoselective Effects in Reactions of Metal Complexes, II selectivity in the complex formation of nickel(II)-, copper(II)-and zinc(II)-(D)-propylenediaminetetraacetate with racemic 1-phenylethyl-amine [1]

The selectivity in the formation of mixed complexes of optically active metapropylenediaminetetraacetates with 1-phenylethyl-amine has been investigated by chromatography and by liquid-phase distribution measurements for the three metal ions Ni2+, Cu2+ and Zn2+. The selectivity is found to be sufficiently high to allow the chromatographic resolution of the racemic amine.
