✦ Synopsis

Swwnary. The kinetics o f thc formation and dissociation of the copper(I1) complex with X, N'-Diglycyl-propylendiainine has been studied. In the formation reaction an interrncdiate mas observed, the structure and reactivity of which is discussed. The rate of dissociation of the complex is proportional to [H+l2. This is explained by a rapid proton addition to one of the amino groups, followed by the slow reaction of a second proton with the coordinated amide group. The effect of acetate buffer, which increases the dissociation rate, is tliscussed.

In einer fruheren Arbeit [l] wurde die Gleichgewichtsreaktion zwischen Cu2+ und einer homologen Reihe von Bisamiden (I) untersucht. Dabei zeigte sich, dass Cuzf,
