Extended analogues of tetrathiafulvalene (TTF): 1,2-bis, 1,4-bis and 1,2,4,5-tetrakis(1,4-dithiafulven-6-yl) benzenes; Synthesis and π-donor abilities.
The title compounds are prepared by Wittig or Wittig-Horner reactions between the corresponding benzenes di- and tetracarbaldehydes and the P-reagents W or P bearing the 1,3-dithiol-2-ylidene moiety; among them, the tetrakis(dithiafulvenyl)benzene 3c is shown by cyclic voltammetry to possess the best pi-donor character and, also, is chemically or electrochemically oxidized.

The synthesis and electrochemical redox properties of a series of symmetrical, highly conjugated bis(benzo-1,3-dithiole) and bis(benzothiazole) derivatives (8)–(24) are described. The heterocyclic end-groups are linked by a conjugated framework that incorporates the following groups: (a) phenyl, (b) naphthyl, (c) thienyl, (d) biphenyl, (e) anthracenyl, and (f) benzanthracenyl. Compounds (13) and (16)–(19)
