Amine ligands play a vital role in transition metal catalysis. Amine groups (-NH₂) are common ligands with rich coordination capabilities and the ability to regulate the electronic properties of metal centers. They can coordinate with metal ions to form stable complexes, thereby changing the chemical environment of the metal center and affecting the efficiency, selectivity and stability of the catalytic reaction. The role of amine ligands in transition metal catalysis is mainly reflected in their ability to regulate the electronic properties of metals, affect the coordination environment, promote the activation of reactants, improve catalytic selectivity and stabilize metal catalysts. In the field of catalysis, amine ligands are widely used in organic synthesis, reduction reactions, asymmetric catalysis, metal-organic reactions and other directions. They are important tools for designing efficient catalysts and improving catalytic reaction performance.
