Description

Application

N,N′-Dimethylethylenediamine can be used as a ligand in the following processes:
• Copper-catalyzed cyanations of aryl bromides using potassium hexacyanoferrate(II) to form the corresponding benzonitriles.
• Copper-catalyzed tandem reaction of carbodiimide and isocyanoacetate to form benzoimidazo[1,5-α]imidazoles.
• Aminothiolation of 1,1-dibromoalkene to form N-fused heterocycles.
• In combination with ferrous chloride, for the N-arylation of NH-sulfoximines with aryl iodides to form N-arylsulfoximines.
• It can catalyze the direct C-H arylation of unactivated benzene in the presence of potassium tert-butoxide to form the corresponding biaryl.
