Abstract
A cross-coupling of aryl tosylates with amines and anilines was achieved by using a Pd-NHC system based on the popular Pd-PEPPSI precatalyst. The NHC ligand incorporates two dimethylamino groups as backbone substituents for enhancing both the electronic and steric properties of the carbene.
