  PMDTA, formally N,N,N′,N′,N′′-pentamethyldiethylenetriamine, is an organic compound with the formula [Me2NCH2CH2]2NMe (Me is CH3). PMDTA is a basic, bulky, and flexible, tridentate ligand that is a used in organolithium chemistry.
  Synthesis
  PMDTA is prepared by methylating diethylenetriamine with formaldehyde and formic acid.
  [H2N(CH2)2]2NH + 5 CH2O + 5 HCO2H → [Me2NCH2CH2]2NMe + 5 CO2 + 5 H2O
  Comparison with diethylenetriamine
  Unlike diethylenetriamine, all three amines in PDMTA are tertiary. Both PMDTA and diethylenetriamine are tridentate ligands that form two five-membered chelate rings. The σ-donating properties of the amino groups of diethylenetriamine are greater than that of PMDTA in copper(II) complexes. Both ligands can coordinate metal complexes in arrangements where the three nitrogen centers are co-planar or mutually cis.
