Description

Nonafluorobutanesulfonyl Fluoride 90%
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[3][4]and in Buchwald-Hartwig amination.
Purpose
For R&D use onlynot for drug household or other uses.
General Description
Perfluorobutanesulfonyl fluoride (nonafluorobutanesulfonyl fluoride NfF) is a colorless volatile liquid that is immiscible with water but soluble in common organic solvents. It is prepared by the electrochemical fluorination of sulfolane. NfF serves as an entry point to nonafluorobutanesulfonates (nonaflates) which are valuable as electrophiles in palladium catalyzed cross coupling reactions. As a perfluoroalkylsulfonylating agent NfF offers the advantages of lesser cost and greater stability over the more frequently used triflic anhydride.
