title: Polyhalogenated heterocyclic compounds. Macrocycles from perfluoro-4-isopropylpyridine.
abstract: Perfluoro-4-isopropylpyridine was used as a building block for the two-step synthesis of a variety of macrocyclic systems bearing pyridine sub-units which were characterised by X-ray crystallography. Electrospray mass spectrometry revealed that complexation of either cations and, unusually, anions is possible depending on the structure of the macrocycle.
