5,6-Dihydro-2-dimethylamino-1,3-dithiolo[4,5-b][1,4]oxathiin-2-ium hexafluorophosphate 8 was synthesized in four steps from 1,4-oxathiane in â 19% yield. 8 was converted to the corresponding 1,3-dithiole-2-thione 9 and subsequently 1,3-dithiol-2-one 10. A 1:1 mixture of 9 and 10 was coupled in trimethyl phosphite to the title compound 3 in 35% yield.
5,6-二氢-2-二甲基氨基-1,3-二硫环戊并[4,5-b][1,4]氧硫杂环戊烯-2-鎓六氟磷酸盐 8 由 1,4-氧硫杂环戊烯经四个步骤合成,收率为 19%。8 被转化为相应的 1,3-二硫杂环戊烯-2-硫酮 9,随后又转化为 1,3-二硫杂环戊烯-2-酮 10。9 和 10 的 1:1 混合物在亚磷酸三甲酯中偶联生成标题化合物 3,收率为 35%。
