4-Sulfoalkanoic acids are a class of important dianionic-headed surfactants. Various 4-sulfoalkanoic acids with straight C8, C10, C12, C14, C16, and C18 chains were synthesized expeditiously through the radical addition of methyl 2-((ethoxycarbonothioyl)thio)acetate to linear terminal olefins and subsequent oxidation with peroxyformic acid. This is a useful and convenient strategy for the synthesis of dianionic-headed surfactants with a carboxylic acid and sulfonic acid functionalities in the head group region.
4-磺基链烷酸是一类重要的双阴离子头基表面活性剂。通过将2-((乙氧基羰基硫代)硫代)乙酸甲酯自由基加成到直链末端烯烃上，随后用过氧甲酸氧化，快速合成了具有直链C8、C10、C12、C14、C16和C18链的各种4-磺基链烷酸。这是一种在头基区域合成具有羧酸和磺酸官能团的双阴离子头基表面活性剂的有用且便捷的策略。
