1，3，4，6－四硫代戊搭烯－2，5－二酮制备含硫取代基的四硫富瓦烯的研究

Preparation of Tetrathiafulvalene Derivatives Containing Sulfur Substituting Groups from 1, 3, 4, 6-Tetrathiapentalene

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．

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 using 1, 3, 4, 6-tetrathiapentalene-2,5-dione as the starting material. A reasonable 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.
