Annelides. 3. Complexation of Dioxygen in Organized Cobaltous Complex Assemblies. A New Approach to Kinetic Studies in Micellar Phases

Article abstract of DOI:10.1021/ja00544a013

Amphiphilic ligands belonging to the Annelide class are synthesized and shown to form complexes with transition-metal cation.By aggregation, these complexes can be organized into supermolecular structures.For the first time, it is shown that the formation of micellar phases of cobaltous complexes can lead to a dramatic enhancement of the dioxygen stability constant.Kinetic measurements have been performed to elucidate the mechanism of complexation and, in particular, the respective contributions of the local concentrations, the dimensionality of the reaction, and the orientation of the reactants upon the micellar effect.A new theoretical approach is presented to rationalize the chemical reactions in micellar phases by using the Prigogine-Flory model.
