A novel macrocycle containing the 4,5-dithio-1,3-dithiole-2-thione unit and a related macrocycle incorporating the tetrathiafulvalene moiety

Abstract

A novel macrocycle (3) incorporating the 4,5-dithio-1,3-dithiole-2-thione unit has been prepared from 2,6-bis(bromomethyl)pyridine and 4,5-bis(benzoylthio)-1,3-dithiole-2-thione: intramolecular triethylphosphite coupling of (3) leads to a novel macrocyclic π-donor (4) incorporating a non-planar tetrathiafulvalene moiety; the crystal structures of (3) and (4) are reported.
