producing a rather stable carbonium ion, the thioether gives the chloride and an olefin, which are derived from the cation, the latter reacting also with the sulfenyl chloride to give adducts. There is another path to afford alkyl chloride; that is, an SN2-type reaction takes place when the alkyl part gives a less stable carbonium ion. The third and fourth products are α-chloro sulfide and α,β-unsaturated
发现硫醚与亚磺酰氯反应生成四种产物。当硫醚的烷基部分能够产生相当稳定的碳正离子时,硫醚产生氯化物和衍生自阳离子的烯烃,后者也与亚磺酰氯反应产生加合物。还有另一种途径可以提供烷基氯;也就是说,当烷基部分产生不太稳定的碳正离子时,会发生 SN2 型反应。第三和第四种产品是α-氯硫化物和α,β-不饱和硫化物,它们似乎是通过一个共同的中间体生产的。后者可与亚磺酰氯进一步反应得到烯二硫醇衍生物。
