Summary (AI generated)

The application of 3D metals is still limited due to poor reactivity and selectivity. Low covalent 3D metals easily lose electrons, weakening the D orbital's ability to accept electrons from π bonds. The volatile balance of spins and coordination models makes it difficult for D electrons to fill back into the π* bond. Small atomic radius can lead to ligand dissociation, further decreasing reactivity and selectivity. Our strategy is to use a design strategy to control selectivity.
