“…[47] For example, exposure of alkyl sulfonyl fluorides to potassium fluoride was shown to assist hydrolysis in the presence of traces of water. [48] The answer to this problem has been available since 1949, when the reaction of sulfonyl chlorides with potassium bifluoride (a reagent first introduced into organic chemistry, as far as we can tell, by Borodin in 1863) [49] was described in a patent by Pound and Saunders. [50] However, the literature contains only a handful of reports employing this "acidic", but more nucleophilic, form of fluoride ion for the preparation of sulfonyl fluorides.…”

“… 12 While this approach often gave quantitative yields for aryl sulfonyl fluorides, alkyl sulfonyl fluorides were prone to undesired side reactions. 13 Potassium bifluoride – KFHF 14 – as an acidic, yet more nucleophilic form of fluoride, helped to mitigate the undesired side reactions. 15 In these biphasic reactions, it is proposed that nucleophilic fluoride anions (F − ) are liberated from bifluoride anions (FHF) − by destabilization of fluoride–HF hydrogen bonding interactions at the non-protic organic phase interface.…”

“…[47] Zum Beispiel wurde gezeigt, dass die Zugabe von Kaliumfluorid die Hydrolyse von Alkylsulfonylfluoriden in der Gegenwart von Spuren von Wasser unterstützt. [48] Die Lçsung für dieses Problem gibt es seit 1949, als Pound und Saunders [50] in einem Patent die Reaktion von Sulfonylchloriden mit Kaliumbifluorid (einem Reagens, das unseres Wissens 1863 von Borodin in die organische Chemie eingeführt wurde) [49] beschrieben. In der Literatur finden sich jedoch nur sehr wenige Berichte, in denen diese "saure", aber nukleophilere Form von Fluoridionen für die Herstellung von Sulfonylfluoriden eingesetzt wurde.…”
