thiophenols and sulfur dichloride, reacted with olefins to give disulfide adducts, which could easily be transformed into episulfides in good yields by treatment with sodium amide or sulfide. The episulfidation of olefins has been shown to be stereospecific, since trans- and cis-2-butenes afforded the corresponding trans and cis episulfides, respectively.
芳烃硫磺酰氯很容易由相应的苯硫酚和二氯化硫制备,与烯烃反应生成二硫化物加合物,通过用氨基钠或硫化物处理,可以很容易地将其转化为环硫化物,产率很高。烯烃的环硫化已被证明是立体有择的,因为反式和顺式 2-丁烯分别提供相应的反式和顺式环硫醚。
