Abstract
Abstract Palladium-catalyzed aryl amination of 2,6-dibromopyridine with 2,6-bis(methylamino)pyridine or 2-bromo-6-(methylamino)pyridine gave new azacalix[ n ](2,6)pyridines ( n =4 and 6). Molecular structure, conformation, and complexation of the macrocycles toward zinc ion were characterized by NMR spectroscopy and X-ray crystallography.
