Tris(2-pyridylmethyl)amine (abbreviated TPMA or TPA) is an organic compound with the formula (C5H4NCH2)3N. It is a tertiary amine with three picolyl substituents. It is a white solid that is soluble in polar organic solvents. It is a ligand in coordination chemistry.
The ligand is prepared by the alkylation of 2-picolylamine by picolyl chloride: [1]
TPMA is a tripodal ligand, often used to simulate the coordination environment within some proteins. It is also used as a copper ligand in ATRP.
