CAS No:375-72-4
Prdouct Details:

Perfluoro n-butyl Sulfonyl Fluoride

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 electroche-
mical 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 perfluoroalk-
ylsulfonylating agent, NfF offers the advantages of lesser cost and greater stability over the more frequ-
ently used triflic anhydride. The fluoride leaving group is readily substituted by nucleophiles such as
amines, phenoxides, and enolates, giving sulfonamides, aryl nonaflates, and alkenyl nonaflates respe-
ctively. However, it is not attacked by water (in which it is stable at pH<12). Hydrolysis by barium hydroxi-
de gives Ba(ONf)2, which upon treatment with sulfuric acid gives perfluorobutanesulfonic acid and ins-
oluble barium sulfate.
