This content is a preprint and has not undergone peer review at the time of posting.


Ambidentate ligand pyridyldiketones were used in combination with copper to catalyze amination of aryl halides under very mild temperatures with aqueous ammonia. This novel catalytic system allow efficient coupling in one of the smoothest conditions ever reported in literature.
