35 - 135New Vinylogous Tetrathiafulvalene π-Electron Donors with LowerOxidation Potentials. — Mild and efficient syntheses of new vinylogoustetrafulvalenes (VI) and 1,3-dithiole-2-thiones (V) via base-catalyzed ringopening of (III) are described. Cyclic voltammetry establishes that the newdonors (VI) have significantly lower solution oxidation potentials than thealready known organic superconductor bis(ethylenedithiol) tetrathiafulvaleneand therefore behave as good precursors for organic metals. — (YU, L.; ZHU,D.; Chem.
