The cross-coupling of aryl tosylates with amines and anilines was achieved by using for the first time a Pd-NHC system based on the popular Pd-PEPPSI precatalyst platform in which the anchoring imidazol-2-ylidene ligand IPr(Nme2)2 incorporates two dimethylamino groups as backbone substituents enhancing both the electronic and steric properties of the carbene. The system optimization and its application scope are disclosed.

Some secondary and primary aromatic amines were variously N-alkylated and N-peralkylated by the aldehyde-sodium borohydride procedure in acidic aqueous solution. The procedure lends itself to the alpha-mono and alpha,alpha'-dideuterium labelling of the new N-substituent(s).
