Aryl propargyl sulfides were subjected to electrochemical fluorination in dimethoxyethane (DME) containing various fluoride supporting electrolytes using an undivided cell to provide the corresponding α-monofluorinated or α,α-difluorinated sulfides selectively as main products in good yields depending on the amount of electricity passed. The α,α-difluorinated sulfides were stable enough to be isolated
芳基炔丙基硫醚在含有各种氟化物支持电解质的二甲氧基乙烷(DME)中使用不分隔的电池进行电化学氟化,以选择性地提供相应的α-单氟化或α,α-二氟化硫化物作为主要产物,取决于通过的电量,从而获得高收率。α,α-二氟硫化物很稳定,可以分离出来,而α-单氟硫化物非常不稳定。α-单氟化硫化物易于以良好的产率转化为相应的稳定的α-单氟烯丙基硫化物。此外,还研究了α-单氟烯丙基硫化物的合成效用。
