tripodal TripTOX ligands, based on the rigid triptycene backbone, and on their successful application in the asymmetric copper-catalyzed aziridination reaction. The ligand showed good to excellent performance in the copper-catalyzed asymmetric aziridination of chalcones. The catalyst derived from the new ligand appears to be the catalyst of choice when substrates have a coordinating nature.
Capturing the Trajectory of Metal-Ion-Cluster Formation: Stepwise Accumulation of Zn(II) Ions in a Robust Coordination Space Formed by a Rigid Tridentate Carboxylate Ligand
ligand-directed synthesis of metal-ion clusters with a well-defined number and arrangement of metal ions is an important subject toward the development of functional inorganic–organic nanohybrids. Here we report the synthesis of multinuclear Zn–oxo clusters using a triptycene-based rigid ligand (H3L) featuring three metal-coordination sites arranged in a triangular shape. Upon complexation of H3L with
