Abstract
Novel functionalized bis(ethylenedithio)tetrathiafulvalene (BEDT–TTF) derivatives 4 and 5 have been synthesized in good yields from cyano precursor via a cross-coupling reaction. Their redox potentials have been studied by cyclic voltammetry in a dichloromethane solution; this indicated that they are slightly weaker electron donors than BEDT–TTF. Compound 4 has been studied by X–ray crystallography; this revealed that, in the crystal, the molecules were held together by some unconventional C–H···N and C–H···S hydrogen bonds.

De nouveaux dérivés fonctionnalisés du bis(éthylènedithio)tétrathiafulvalène (BEDT–TTF), 4 et 5, ont été synthétisés avec de bons rendements à partir d’un précurseur cyano via une réaction de couplage croisé. L’étude de leurs potentiels redox par voltamétrie cyclique dans une solution de dichlorométhane indique qu’ils sont des donneurs d’électrons légèrement plus faibles que le BEDT–TTF. L’étude du composé 4 par cristallographie des rayons X révèle que, dans le cristal, la cohésion des molécules est maintenue par des liaisons hydrogène C–H···N and C–H···S non conventionnelles.
