3-dithiolan-4-yl)methyl dialkylcarbamothioates (3) and S-thiiran-2-ylmethyl dialkylcarbamothioate (5) has been reported by the reaction of 5-(chloromethyl)-1,3-oxathiolane-2-thione (1) with sodium dialkylcarbamodithioate (2) and dialkylamine (4), respectively, through intermolecular O−S rearrangement in water. A plausible mechanism of formation of the title compounds has also been proposed.
据报道,通过5-(氯甲基)的反应可以轻松合成S-(2-硫代-1,3-二硫杂环戊-4-基)甲基二烷基氨基甲酸酯(3)和S-噻喃-2-基甲基二烷基氨基甲酸酯(5)。 -1,3-氧杂硫杂环戊烷-2-硫酮(1)与二烷基氨基甲磺酸二钠(2)和二烷基胺(4)通过在水中的分子间OS重排。还提出了标题化合物形成的合理机理。
