2-Picolylamine is an organic compound with the formula H₂NCH₂C₅H₄N. A colorless liquid, it is a common bidentate ligand and a precursor to more complex multidentate ligands such as tris(2-pyridylmethyl)amine. It is usually prepared by hydrogenation of 2-cyanopyridine. One such complex is Baratta's catalyst RuCl₂(PPh₃)₂(ampy) (ampy = 2-picolylamine) for transfer hydrogenation.^[2] Salts of the complex [Fe(pyCH₂NH₂)₃]²⁺ exhibit spin crossover behavior, whereby the complex switches from high to low spin configurations, depending on the temperature.^[3]

Safety[edit]

The oral LD₅₀ in quail is low, being 750 mg/kg.^[4]
