Abstract

Abstract: A new demetallation method for Cu(I)‐bound catenanes that contain a strong binding bis(phenanthroline) cavity using the bidentate ethylenediamine is reported. Cu(I) extraction using the organic diamine is mild, convenient and efficient, and the metal can be removed from the kinetically stable catenane complexes in various solvents within 5 minutes, offering an alternative strategy to the use of toxic cyanide in competing for the Cu(I) coordination. Abstract : In contrast to the conventional use of the strong and monodentate cyanide ligand, kinetically stable Cu + ‐catenane complexes can be demetallated by the bidentate ethylenediamine within 5 minutes in various common organic solvents. The procedure is mild, safe, convenient and efficient, providing the metal‐free catenane in good yields.
