 | Hazard Information | Back Directory |  | [Description] 
 1,1,2,2,3,3,4,4,4-Nonafluorobutane-1-sulfonyl fluoride
(NfF,375-72-4) also called Nonafluorobutanesulfonyl fluoride is a versatile compound in organic synthesis. It can be
used as a fluoride source for the nucleophilic introduction
of fluorine, but it is also frequently applied as sulfonylation
reagent generating intermediates with strong electron withdrawing perfluorinated alkyl substituents.
 |  | [Chemical Properties] 
 CLEAR COLORLESS LIQUID
 |  | [Uses] 
 Benzynes were generated from o-(trimethylsilyl) phenols using nonafluorobutanesulfonyl fluoride (NfF) by a domino process.Nonafluorobutanesulfonyl fluoride (nonaflyl fluoride, C 4 F 9 SO 2 F, NfF) is the most widely used commercially available reagent for the synthesis of nonaflates.
 |  | [Application] 
 Perfluoro-1-butanesulfonyl fluoride (NfF,375-72-4) reacts with alcohols, including phenols, to yield nonafluorobutanesulfonate esters (nonaflates). Nonaflates can be used as electrophiles in several palladium-catalyzed cross coupling reactions and in Buchwald-Hartwig amination. NfF can also be used to prepare aryl nonaflates by reacting with corresponding aryloxysilanes in the presence of fluoride ion.
 |  | [reaction suitability] 
 reaction type: click chemistry
 |  | [Synthesis] 
 NfF(Nonafluorobutanesulfonyl fluoride,375-72-4) is produced on industrial scale by anodic fluorination of sulfolene (1, Scheme 1),3 therefore it is a fairly cheap reagent and commercially available from several suppliers. The compound is bench-stable and storable for years, nontoxic and easy to handle.
 
   |  | [storage] 
 Store in amber colored bottles protected from light; for prolonged storage, PVC bottles are recommended.
