N,N'-Dimethylethylenediamine (DMEDA) is the organic compound with the formula (CHNH)CH. It is a colorless liquid with a fishy odor. It features two secondary amine functional groups. Regarding its name, N and N' indicate that the methyl groups are attached to different nitrogen atoms.
Reactions DMEDA is used as a chelating diamine for the preparation of metal complexes, some of which function as homogeneous catalysts.Chan, Timothy R.; Hilgraf, Robert; Sharpless, K. Barry; Fokin, Valery V. "Polytriazoles as copper(I)-stabilizing ligands in catalysis" Organic Letters 2004, volume 6, 2853-2855.
The compound is used as a precursor to imidazolidines by condensation with ketones or with aldehydes:
DMEDA complexes of copper(I) halides are used to catalyze C-N coupling reactions.
