酮与 CS2 和 2 当量的 KH 在 THF-N,N'-二甲基丙烯脲溶液中反应生成 3-氧代二硫代酸的二价阴离子。通过六甲基二硅硫烷和氧化剂如六氯乙烷的连续作用，这些二价阴离子以良好的收率转化为3H-1,2-二硫醇-3-硫酮。 (C) 2000 Elsevier Science Ltd. 保留所有权利。
Reaction of ketones with CS2 and 2 equivalents of KH in THF-N,N'-dimethylpropyleneurea solution produces the dianions of 3-oxodithioic acids. These dianions are converted in good yield to 3H-1,2-dithiole-3-thiones by the sequential action of hexamethyldisilathiane and an oxidizing agent such as hexachloroethane.
