摘要：

Micelles made up of lipophilic ligand 2a and Cu2+ or Zn2+ ions show catalytic properties in the cleavage of the pnitrophenylester of picolinic acid (PNPP). in the case of the Cu+ complex comparison with the non-micellar model 3a and the Omethylated siblings clearly shows how only the supramolecular assembly leads to catalysis with involvement of the hydroxyl as the nucleophile. A stereochemical modification of the complex in the aggregate is suggested as a likely explanation of the observed phenomena. © 1990.
