Metal complexes based on a bis(2-pyridylmethyl)amine-based scaffold and methods of making the same
A catalyst includes a bis(2-pyridylmethyl)amine-based ligand. A method of forming a catalyst, may include: reacting bis(2-pyridylmethyl)amine-based compound with a terminal azide and/or a terminal alkyne in the presence of Cu(I) to form a bis(2-pyridylmethyl)amine-based ligand. A method of using such catalysts may include neutralizing toxicity of at least one organophosphorus-based compound by reacting the organophosphorus-based compound with a bis(2-pyridylmethyl)amine-based ligand-metal complex.
