development of this procedure has been the synthesis of a sulfonium salt bearing a trifluorovinyl substituent. This reagent suffers the addition of alcohols to the activated double bond and subsequently generates alkyl fluoride radicals by mesolytic cleavage of the S−C bond after one electron reduction.
