Hepta‐Coordinated Alkaline‐Earth Complexes Featuring <i>E^N^N^N^E</i> (E = BH <sub>3</sub> , S, Se) Ligands as Efficient Catalysts for Heterocumulene Hydroboration and Cyclic Ester Ring‐Opening Polymerization
). Solid state structures of ligands (2-H2, and 3-H2) and metal complexes (1a, 1b, 2b, 2c, 3a, and 3b) reveal that non-planar coordinating sites of ligands (N, P, E) enforce a co-planar penta-coordination to alkaline earth metals (Mg, Ca, Sr). Moreover, the Ae metal complexes exhibited multitasking catalytic activity for the hydroboration of heterocumulenes (e.g., isocyanates and carbodiimides) and the ROP polymerization of cyclic esters (rac-lactide, ε-caprolactone).
