General description

N,N,N′,N′-Tetramethylethylenediamine (TMEDA) is a bidentate tertiary amine. It is a Lewis base having good solvating properties. It is useful ligand for organolithium chemistry. Ultrafast molecular structural dynamics of the charge transfer in N,N,N′,N′-tetramethylethylenediamine has been studied by Rydberg fingerprint spectroscopy.
