Beschreibung

Anwendung

Perfluoro-1-butanesulfonyl fluoride (NfF) 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.
