Multidentate ligand kinetics. V. Copper(II) and cyclohexylenediaminetetraacetatonickelate(II)

The kinetics of the substitution reaction between the hydrated copper(II) ion and the cyclohexylenediaminetetraacetatonickelate(II) ion are studied from pH 1.5 to 3.5. In contrast to the dominant role of copper ion attack in the similar reaction with ethylenediaminetetraacetatonickelate(II), there is no copper ion attack of cyclohexylenediaminetetraacetatonickelate(II). The reaction is first order in the complex and independent of copper concentration but it is highly pH dependent. The acid dissociation rate constants are resolved. The absence of any copper dependence is attributed to the inability of the ion to form dinuclear iminodiacetate intermediates because of hindered rotation and steric blocking due to the hydrocarbon ring. The proposed mechanism indicates that nickel-nitrogen bond dissociation must be a rate-determining step in these multidentate ligand exchange reactions.

Multidentate ligand kinetics. VIII. The effect of hydroxide, acetate, and azide complexes of copper(II) in its reaction with ethylenediaminetetraacetate complexes

The kinetics of the reaction of copper(II) with the ethylenediaminetetraacetatozincate(II) and -nickelate(II) complexes are studied in the presence of various anions at 25.0° and an ionic strength of 0.10. From pH 5 to 7, the rate of the exchange reaction
