    Abstract: Hydrocarbylethyl sulfonyl fluorides in which the hydrocarbyl substituent contains at least 3 carbon atoms, can be prepared by reacting 2-mercaptoethanol with chlorine to form chloroethyl sulfonyl chloride which is treated with aqueous potassium fluoride to yield chloroethyl sulfonyl fluoride, followed by treatment with magnesium oxide to yield vinyl sulfonyl fluoride. The vinyl sulfonyl fluoride is adducted to a hydrocarbyl substituent precursor, such as an olefin or halogenated olefin. A representative compound is polyisobutenyl sulfonyl fluoride. The hydrocarbylethyl sulfonamide products for which the hydrocarbylethyl sulfonyl fluorides are intermediates are useful as additives for lubricating oils.

    Abstract translation: 其中烃基取代基含有至少3个碳原子的烃基乙基磺酰氟可以通过使2-巯基乙醇与氯反应形成氯乙基磺酰氯,用氟化钾水溶液处理,得到氯乙基磺酰氟,然后用氧化镁处理 产生乙烯基磺酰氟。 乙烯基磺酰氟加成烃基取代基前体,如烯烃或卤代烯烃。 代表性的化合物是聚异丁烯基磺酰氟。 烃基乙基磺酰氟是其中间体的烃基乙基磺酰胺产物可用作润滑油的添加剂。
