The synthesis of the fluorinated 4,5-(2,2'-difluoropropylenedithio)-1,3-dithiol-2-one heterocycle with DAST allows for the preparation of several symmetrical and unsymmetrical di- and tetrafluoro-substituted tetrathiafulvalenes with accessible oxidation potentials (0.6 < E1(1/2) < 0.85 V vs SCE) despite the presence of the electron-withdrawing CF2 groups. The flexibility of the fluorinated seven-membered
用DAST合成氟化的4,5-(2,2'-二氟丙烯二硫基)-1,3-二硫醇-2-酮杂环可以制备几种对称和不对称的二氟和四氟取代的四硫富瓦烯,它们具有可及的氧化势尽管存在吸电子CF2基团(相对于SCE,0.6
