General description

trans-N,N′-Dimethylcyclohexane-1,2-diamine is a ligand used to promote N-alkenylation and N-alkylation reactions of amides.

Application

trans-N,N′-dimethylcyclohexane-1,2-diamine can be used as a ligand in the synthesis of the following products via copper catalyzed C-N coupling reactions:
  • vinylsulfoximines obtained from NH sulfoximes and vinyl bromides
  • N-arylpyridones obtained via reaction between 2-substituted pyridines and aryl halides
  • N-aryl amines obtained via reaction between amines and aryl iodides/aryl bromides
