reaction, "thiophilic addition of an organomagnesium reagent onto dithioester-beta-elimination of fluoride-[3,3] sigmatropic rearrangement", provides the product of formal regiospecific substitution of a fluorine atom by an allyl group. This mild and versatile methodology was applied to the synthesis of various alpha-allylic and alpha,alpha-bis(allylic) alpha-trifluoromethyl dithioesters.
三步多米诺反应,“在氟-[3,3]σ重排的二硫酯-β-消除中向硫代酯-β的硫族加成反应”,提供了烯丙基对氟原子进行形式上的区域特异性取代的产物。这种温和而通用的方法学被用于合成各种α-烯丙基和α,α-双(烯丙基)α-三氟甲基二硫酯。
