摘要： 以1,3,4,6-四硫代戊搭烯-2,5-二酮为原料,经偶联、醇解、烃化或醇解、烃化、偶联等步骤,制得四甲硫基四硫富瓦烯、四乙硫基四硫富瓦烃、二喹喔啉硫醚、4-甲硫基-5-甲氧甲酰硫基-1,3-二硫环戊烯-2-酮、四甲硫基乙烯和4,4'-二甲硫基-5,5'-二甲氧甲酰硫基四硫富瓦烯及它的异构体混合物。提出了1,3,4,6-四硫代戊搭烯-2,5-二酮醇解机理。讨论了未得到某些预期产物的原因。报道了3种四硫富瓦烯衍生物的循环伏安图及电化学性质。

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
