Resolution and Kinetic Stability of a Chiral Supramolecular Assembly Made of Labile Components

Resolution and Kinetic Stability of a Chiral Supramolecular Assembly Made of Labile Components

Enough mechanical stiffness that the metal centers can no longer racemize is provided by the connection of four labile metal centers (AlIII, GaIII, InIII, FeIII) and six achiral bis‐catecholate ligands in a rigid tetrahedral assembly (see picture). The resolution and unprecedented kinetic stability...

Zusammenfassung:Enough mechanical stiffness that the metal centers can no longer racemize is provided by the connection of four labile metal centers (AlIII, GaIII, InIII, FeIII) and six achiral bis‐catecholate ligands in a rigid tetrahedral assembly (see picture). The resolution and unprecedented kinetic stability of such a chiral supramolecular assembly is reported here for the first time.
