- Die in der deutschen Patentschrift 1275 052 beschriebenen Perfluoralkansulfonsäurertuoralkylester sind wirksame Fluoralkylierungsmittel für nukleophile Verbindungen. Erfindungsgemäß wird ein Verfahren zur Fluoralkylierung nukleophiler Verbindpngen vorgeschlagen, das dadurch gekennzeichnet ist, daß man einen nukleophilen Reaktionspartner mit einer Nukleophilivätskonstanten oberhalb von 1 mit einem Sulfonsäureester der allgemeinen Formel (RfS O2OCH2),,Q, in der Rf einen perfluorierten Alkylrest mit 1 bis 8 Kohlenstoffatomen, Q einen hochfluorierten Alkylrest mit der Valenz m, der mindestens Gewichtsprozent Fluor enthält, und m = 1 oder bedeutet, in praktisch stöchiomelrischen Mengen in einem für die beiden Umsetzungsteilnehmer inerten organischen Lösungsmittel umsetzt.Als nukleophile Reaktionspartner können z. B. die folgenden verwendet werden:
