through a sulfonium–Claisen-type rearrangement. This reaction enables the incorporation of two valuable functional groups, such as the cyanomethyl group and the fluoroalkylthio group, into arenes. Remarkably, fluoroalkylthio groups, such as SCFH2 and SCF2H, bearing active hydrogen, are well tolerated by the reaction. The success of the reaction relies on the use of an excess amount of acetonitrile
我们在此报告了芳基氟烷基亚砜与
乙腈通过锍-克莱森型重排进行的邻位
氰甲基化。该反应能够将两个有价值的官能团(例如
氰甲基和氟烷
硫基)引入
芳烃中。值得注意的是,带有活性氢的氟烷
硫基,例如SCFH 2和SCF 2 H,对反应具有良好的耐受性。该反应的成功依赖于过量
乙腈的使用和
氟代烷基取代基的电负性效应,这两者都促进亚砜与
乙腈的亲电组装。因此,锍-克莱森重排反应可以耐受多种带有卤化物、腈、酮、砜和酰胺等官能团的
氟代烷基亚砜,这对后续的阐述和探索很有吸引力。
