Metalation-Resistant β-Diketiminato Ligands for Thermally Robust Organoscandium Complexes

A new ligand design for the widely used β-diketiminato framework implements a “remote steric bulk” strategy for the stabilization of low-coordinate, metalation-resistant organoscandium complexes. In comparison to standard ligands, substantial improvements in thermal stability for neutral dialkyl and cationic alkyl organoscandium complexes are observed.
