perfluoroalkylated sulfoxides with trifluoromethanesulfonic anhydride behaves as highly electrophilic entities. Their reaction with nitriles allows a Ritter-like process leading to the new fluorinated acylsulfilimines 1–21 after hydrolysis. This flexible methodology allows some variation of both the sulfoxide and nitrile components. Derived acylsulfoximines 22–25 or free sulfoximines 26–28 could be selectively
通过用三氟甲磺酸酐活化全氟烷基化亚砜获得的物质表现为高度亲电实体。它们与腈的反应允许类似 Ritter 的过程,在水解后产生新的氟化酰基硫亚胺 1-21。这种灵活的方法允许亚砜和腈组分有一些变化。根据需要,通过使用廉价且无毒的高锰酸钾进一步控制氧化,可以选择性地获得衍生的酰基亚砜亚胺 22-25 或游离亚砜亚胺 26-28。该氧化可以在分离中间体硫亚胺之后进行,或者更方便地在直接从氟化亚砜中的一锅法中进行。这种多功能、无溶剂、无金属、
