PMDETA
PMDETA, short for N,N,N',N'',N''-pentamethyldiethylenetriamine, is a tertiary polyamine widely used as a coordinating ligand for transition metals. It is derived from diethylenetriamine by exhaustive methylation, resulting in a flexible, sterically hindered ligand with five methyl substituents distributed among three nitrogen atoms. The molecule is typically a colorless to pale yellow liquid that is miscible with water and many organic solvents, and it exhibits strong basic and coordinating properties.
In coordination chemistry and catalysis, PMDETA forms stable complexes with copper(I) and other metals. The Cu(I)-PMDETA
A primary application of PMDETA is in atom transfer radical polymerization (ATRP). When used with copper halides,
Safety and handling: PMDETA is a caustic, corrosive amine and should be handled with appropriate personal protective
