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.
