- -electron donors have vinyl moieties producing extended π-electron delocalization over the substituent phenyl rings at the peripheries. Keywords: bis(ethylenedithio)tetrathiafulvalene; bis(vinylenedithio)tetrathiafulvalene; tetrathiafulvalene; Introduction Tetrathiafulvalene (TTF, 1, Figure 1) was first

The most notable superconductivity was observed with the radical cation salts derived from the electron-donor molecule bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF) as a (BEDT-TTF)2Cu[N(CN)2]Br salt at 12.5 K (resistive onset) [24]. The tetrathiafulvalene (TTF) ring system is one of
Redox active dendronized polystyrenes equipped with peripheral triarylamines
Beilstein J. Org. Chem. 2014, 10, 3097–3103, doi:10.3762/bjoc.10.326
- tetrathiafulvalene (TTF) derivatives [15][16][17][18][19], the corresponding dendronized polymers are rare [20]. One of the major reasons for this seems to be the difficulty in making such structures. However, redox-active dendronized polymers should provide more opportunities to form functional organic materials

- series of compounds by exploiting the unusual 1,4-aryl shift observed for electron-rich 1,3-dithiole-2-thione and tetrathiafulvalene (TTF) derivatives in the presence of perchloric acid. The mechanistic features of this rearrangement are discussed since this synthetic strategy provides an alternative

- of considerable selectivity in their reductions of organic substrates, and evidence is steadily accumulating to support this. Tetrathiafulvalene (TTF, 1, E11/2 = 0.37 V; E21/2 = 0.67 V in DCM vs SCE) [1], one of the weakest of these donors, reduces arenediazonium salts to aryl radicals [2][3][4][5][6
