Title (EN) PERFLUOROALKYLATION METHOD AND REAGENT THEREFOR
(FR) PROCEDE UTILE POUR LA PERFLUOROALCOYLATION ET REACTIF POUR METTRE EN OEUVRE CE PROCEDE
Abstract:
(EN) A perfluoroalkylation method and a reagent therefor are disclosed. The method comprises contacting a material of formula RfH and a base (or a species capable of generating a base) with a substrate bearing at least one electrophilic function in a polar anhydrous medium. The method is useful for organic synthesis.
(FR) La présente invention a pour objet un procédé utile pour la perfluoroalcoylation ainsi qu'un réactif pour mettre en oeuvre ce procédé. Ce procédé se définit en ce qu'il comporte une étape de mise en contact d'un matériau de formule RfH et d'une base (ou une espèce susceptible d'engendrer une base) avec un substrat porteur d'au moins une fonction électrophile dans un milieu polaire et anhydre. Application à la synthèse organique.
