- On the mechanism of formation of 1,4,5,8-tetrathianaphthalene (TTN) from dimercaptoisotrithione (dmit) derivatives
-
The mechanism of formation of TTN (an important precursor to tetrathiafulvalene (TTF)) from 4,5-bis(benzoylthio)-1,3-dithiole-2-thione is discussed. Contrary to previous reports, ethylenetetrathiolate is not an intermediate in this synthesis, whereas 4,5-vinylenedithio-1,3-dithiole-2- thione is likely to be. The latter is prepared by a new synthesis and converted into TTN in one step. (C) 2000 Elsevier Science Ltd.

- Synthesis, structure and electrochemical properties of two new unsymmetrical tetrathiafulvalene derivatives

Two new unsymmetrical tetrathiafulvalene (TTF) derivatives, 2,3-bis(cyanoethylthio)-6,7-(methylethylenedithio)tetrathiafulvalene (6a) and 2,3-bis(cyanoethylthio)-6,7-(cyclopentodithio)tetrathiafulvalene (6b), have been prepared and characterized by NMR, MS, IR and Elemental analyses. The molecular structures have been determined by X-ray crystallography. Their redox properties have been investigated by cyclic voltammetry in dichloromethane solution and each compound shows two reversible single-electron redox couples.
