The tuning of heterocyclic isomerization: additional routes to extended donors

Tetrathianaphthalene: A precursor easily synthesized in bulk, is utilized in the synthesis of tetrathiafulvalene, and extended chalcogenated tetrathianaphthalenes and tetrathiafulvalenes. The donor syntheses dependant upon core heterocycle configuration retention or isomerization are controlled via the use of novel solvent systems and new classes of disulfide building blocks.
