Abstract
The TTF-like bidentate sulfur nucleophiles 13a,b have been prepared from the corresponding 4,5-dialkyl-1,3-dithiole S-oxides 11a,b, obtained by the oxidation of the parent 1,3-dithioles 10a,b. The aromatic nucleophilic substitutions of tetrachloropyrazine by these nucleophiles 13a,b yield, in a single step, the unsymmetrically substituted pyrazino-TTF 8 or the pyrazine-fused bis-TTF 9a,b depending on the stoeichiometries of the reactions. The electrochemical properties of these new donors, obtained by cyclic voltammetry, are also reported.
