title: Macrocycles from perhalogenated heterocycles.
abstract: Perhalogenated heteroaromatic systems, such as trichloro-s-triazine and pentafluoropyridine, are multifunctional "building blocks" that react with a number of appropriate difunctional nucleophiles to provide access to a variety of macrocyclic and even cage-like molecular architectures. Unusual structural and complexation characteristics of the systems reported so far, such as the recognition of anions, provide a further stimulus for the development of this area.
