Application
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.
NfF can also be used to prepare aryl nonaflates by reacting with corresponding aryloxysilanes in the presence of fluoride ion.
