烷硫基四硫富瓦烯的合成及其性质的研究

Synthesis and Properties of Alkylthio Tetrathiafulvalene

分别以 1 ,3,4 ,6-四硫代戊搭烯 -2 ,5-二酮和 4 ,5-二 ( 2′-氰基乙硫基 ) -1 ,3-二硫杂环戊烯 -2 -酮为原料 ,经偶联、醇解、烃化制得四甲硫基四硫富瓦烯和四乙硫基四硫富瓦烯。对两种方法制得产物的产率存在较大差别提出了合理的解释 ,并讨论了 2种四硫富瓦烯衍生物的循环伏安图及有关电化学性质。

Tetramethylthiotetrathiafulvalene and tetraethylthiotetrathiafulvalene have been prepared by means of coupling/alcoholysis/slkylation from 1,3,4,6-tetrathiapentalene-2,5-dione and 4,5-bis(2′-cyanoethylthio)-1,3-dithiole-2-one repectively. A reasonalble mechanism was given for different yield of two prepared ways. The electrochemical nature of the two alkylthiotetrathiafulvalene prepared was studied by cyclic voltammetry.
