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 heteroarylbromides. The reactions were carried out in relative mild conditions and good to excellent yields were obtained.

Substitution by amines of fluorobenzenes containing a meta-substituted electron withdrawing group (EWG), in DMSO at 100 °C over 60 h gave meta-substituted anilinederivatives in isolated yields of up to 98%. The scope of the reaction is explored in terms of reaction conditions and substrates. It is postulated that facile meta-substitutions are facilitated through field stabilisation of the intermediate
