reaction of olefins, benzeneselenenyl chloride, and p-toluenesulfonamide in the presence of zinc(II) chloride affords N-[2-(phenylseleno)alkyl]-p-toluenesulfonamides in good to excellent yields. When combined with alkylation on the carbon atom bearing the phenylseleno group thus introduced and subsequent oxidative or reductive removal of the selenium moiety, this reaction can be utilized in the preparation
烯烃、苯硒基氯和对甲苯磺酰胺在氯化锌 (II) 存在下的反应以良好至极好的产率提供 N-[2-(苯基硒基)烷基]-对甲苯磺酰胺。当与由此引入的带有苯基硒基的碳原子上的烷基化以及随后氧化或还原除去硒部分相结合时,该反应可用于制备各种烯丙基或饱和酰胺。
