from 2-(3′-hydroxypropyl)-1,3-dithiane with thionyl chloride rearranges to 2-(3′-chloropropyl)-1,3-dithiane. Azide ion displacement of the primary alkyl chloride is then faster than [1.4] sulfanyl participation from the thioacetal. An α-chlorosulfide derived from diphenyldithioacetal does not rearrange but undergoes direct displacement to give an α-azidosulfide.
1,3-二硫杂环丁烷经5- exo- tet环化反应取代甲苯磺酸酯,得到双环sulf盐。叠氮化物离子对该4-thia-7a-thioniaperhydroindene的亲核攻击在动力学上有利于打开以生成九元环α-叠氮基硫醚,但2-(3'-叠氮基丙基)-1,3-二硫杂环丁烷是B3LYP /的热力学产物6-31G **计算。由2-(3'-羟丙基)-1,3-二硫杂环丁烷与亚硫酰氯生成的类似sulf盐重排为2-(3'-氯丙基)-1,3-二硫杂环丁烷。伯烷基氯的叠氮化物离子取代速度快于硫缩醛中的[1.4]硫烷基参与。衍生自二苯基二硫缩醛的α-氯硫化物不重排,而是直接置换得到α-叠氮基硫化物。
