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.针对广泛应用的β-二酮亚胺骨架，一种新型的配体设计引入了“远程立体体积”策略，以稳定低配位、金属化抗性的有机钪化合物。与标准配体相比，中性二烷基和阳离子烷基有机钪化合物的热稳定性得到了显著的提升。
