Highly efficient and practical phosphoramidite–copper catalysts for amination of aryl iodides and heteroaryl bromides with alkylamines and N (H)-heterocycles
A highly efficient copper-catalyzed system using phosphoramidite as ligands was applied to N-arylation of alkylamines and N (H)-heterocycles with aryl iodides and heteroaryl bromides. The reactions were carried out in relative mild conditions and good to excellent yields were obtained.
