TRIS(2-DIMETHYLAMINOETHYL)AMINE Usage And Synthesis

Chemical Properties

Clear colorless to yellow liquid

Uses

Tris(2-dimethylaminoethyl)amine is used as an atom transfer radical polymerization (ATRP) ligand for the creation of telechelic polymers. It is a tripodal polyamine ligand and forms complexes with group 1 metals, which is used in alkali-metal-mediated synthetic applications. Further, it is involved in the macrocyclization processes by reacting with tripodal esters in methanol to give tricyclic cryptands.

General Description

Tris[2-(dimethylamino)ethyl]amine (Me₆TREN) is an aliphatic tertiary amine that forms a quadridentate ligand. It is majorly used in atom transfer radical polymerization (ATRP). It is a hexamethyl derivative of (2-aminoethyl)amine, also known as trenMe. It can be prepared by a modification of Ristempart′s synthesis.
