一般描述
N,N-Dimethylethylenediamine (DMEDA) is used as a bidentate ligand in coordination chemistry due to the presence of two nitrogen atoms, one with lone pairs that can coordinate to a metal center. It is used as a ligand and base in Suzuki-Miyaura and Sonogashira coupling reactions, enhancing palladium catalyst stability, and deprotonating alkynes. It acts as a nucleophile and a base, promoting reactions involving proton transfer or nucleophilic attack. It is commonly used in amination reactions to synthesize substituted amines and in epoxide ring openings to form amino alcohols. Additionally, DMEDA serves as a chelating agent, forming stable complexes with transition metals. It acts as a secondary amine in reductive amination to synthesize tertiary amines.
