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

Abstract

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