Despite advances in the scope of palladium-catalyzed CÀN bond-forming reactions through the development of more active catalysts,[1, 2] limitations to the method still remain: 1) In many cases the coupling of substituted heteroaryl halides with amines is still problematic; 2) the N-arylation reactions of nitrogen heterocycles is limited in scope with respect to both coupling partners; 3) chemoselectivity in CÀN bond-forming processes has not been ...
