1,4,8,11-Tetraazaundecane is the organic compound with the formula (H2NCH2CH2NHCH2)2CH2. It is a tetramine, consisting of two primary amines and two secondary amines positioned symmetrically. Like many amines, this compound has a high affinity for carbon dioxide. [1] The compound can be prepared by treatment of 1,3-dibromopropane with excess ethylenediamine. [2]

The compound has been examined often as a ligand in coordination chemistry. It is tetradentate ligand similar to 1,4,7,10-tetraazadecane. [3] By condensation of its nickel(II) complexes with formaldehyde, one can obtain a variety of macrocyclic ligands. [4]
