PREPARATION AND PROPERTIES OF TETRACYANOQUINODIMETHANS FUSED WITH PYRAZINE UNITS

Abstract The title compounds were prepared by a TiCl4-catalyzed condensation reaction of corresponding quinones with malononitrile. The data of the cyclic voltammogram show that the anion radicals of dipyrazino-TCNQ derivatives are thermodynamically stable. The anion radical salts were isolated.
