Highly efficient copper-catalyzed N-arylation of alkylamines with aryl iodides using phosphoramidite as ligand

A mild and highly efficient copper-catalyzed system for N-arylation of alkylamines with aryl iodides using binaphthol-based phosphoramidites as ligands was developed. The phosphoramidite ligands are stable, cost-effective and easily prepared from inexpensive, commercially available starting materials using a simple, efficient method.
