Abstract: Tetramethylthiotertrathiafulvalene,tetraethylthiotetrathiafulvalene,diquinoxalinylsulfur ether,4-methylthio-5-methoxy-carbonylthio-1, 3-dithiole-2-one,tetrakis(metliylthio) ethylene and 4, 4'-dimethylthio-5, 5'-dimethoxycarbonylthio tetrathiafulvalene have been prepared by means of coupling/alcoholysis/alkylation or alcoholysis/alkylation/coupling, and by using1, 3, 4, 6-tetrathiapentalene-2,5-dione as the starting material. Areasonable mechanism was given for alcoholysis of 1,3,4,6-tetrathiapentalene-2,5-dione.The reason for lack of the expected products was discussed.The electrochemical nature of the three tetrathiafulvalene derivatives prepared was studied by cyclic voltammetry.

Key words: Alkylthiotetrathiafulvalene, Diquinoxalinylsulfur ether, Cyclic voltammogram, Alcohlysis ring-opening, Coupling
