Abstract: Catalysis with the main-group metal calcium conventionally relies on σ-bond metathesis to initiate the reactions. Here, we report a calcium aryloxide based on the tridentate β-diketiminato ligand, which shows transition-metal-like reactivity with dialkylamine-boranes H3B·NHR2 (R… read more here.
