Discovery of N-(Naphthalen-1-yl)-N′-alkyl Oxalamide Ligands Enables Cu-Catalyzed Aryl Amination with High Turnovers
摘要:
A Class of N-(naphthalen-1-yl)-N'-alkyl oxalamides have been proven to be powerful ligands, making a coupling reaction of (hetero)aryl iodides with primary amines proceed at 50 degrees C with only 0.01 mol % of Cu2O and ligand as well as a coupling reaction of (hetero)aryl bromides with primary amines and ammonia at 80 degrees C with only 0.1 mol % of Cu2O and ligand. A wide range of coupling partners work well under these conditions thereby providing an easy to operate method for preparing (hetero)atyl amines.

The addition of 4-(N,N-dimethylamino)phenyllithium to nitroarenes in THF (−78°C) affords the corresponding diarylamines in one-pot and the reaction appears to be general in scope. A ‘nitroso’-based mechanism is proposed for this novel nitroreductive N-arylation reaction.
