4,5-Diiodo-4',5'-ethylenedioxy-TTF (EDO-TTFI2) was synthesized in mode
rate yield by the reaction of EDO-TTF with LDA, followed by quenching
with CF3(CF2)(5)I Although EDO-TTF contains electron-withdrawing iodin
e as the substituent, this compound has a similar donor ability to BED
T-TTF. The radical-cation salt (EDO-TTFI2)(2) . ClO4 shows a metallic
conductivity down to 50 K, reflecting the strong I ... O interaction.
