4, 5-Diiodo-4', 5'-ethylenedioxytetrathiafulvalene and Its Metallic Radical Salts
4,5-Diiodo-4′,5′-ethylenedioxy-TTF (EDO-TTFI<SUB>2</SUB>) was synthesized in moderate yield by the reaction of EDO-TTF with LDA, followed by quenching with CF<SUB>3</SUB>(CF<SUB>2</SUB>)<SUB>5</SUB>I. Although EDO-TTF contains electron-withdrawing iodine as the substituent, this compound has a similar donor ability to BEDT-TTF. The radical-cation salt (EDO-TTFI<SUB>2</SUB>)<SUB>2</SUB>·ClO<SUB>4</SUB> shows a metallic conductivity down to 50 K, reflecting the strong I···O interaction.
