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.

CuI/L5 (N,N'-dimethylethylenediamine) proves to be an efficient catalyst system for the amination of arylhalides with guanidines. The same catalyst system is then successfully applied to the one-step synthesis of 1-H-2-amino-benzimidazoles through tandem aminations of 1,2-dihaloarenes in modest yields. This methodology
