intermediate with another molecule of episulfide, followed by intramolecular oxidation of two sulfur units. When using bis(trimethylsilyl)selenide, the reaction with thiiranes and TBAF affords a smooth access to a novel class of disubstituted-1,2,5-dithiaselenepanes.
双(三甲基甲硅烷基)硫化物在四丁基氟化铵(TBAF)催化下与不同取代的硫杂环丙烷反应,通过硫硅烷中间体与另一分子环硫化物的区域选择性反应合成 3,7-二取代-1,2,5-三硫杂环丙烷,然后是两个硫单元的分子内氧化。当使用双(三甲基甲硅烷基)硒化物时,硫杂丙烷和 TBAF 的反应可以顺利获得一类新的二取代-1,2,5-二硫杂硒烷。
