What is Nonafluorobutanesulfonyl Fluoride (375-72-4)?

Nonafluorobutanesulfonyl fluoride (NFF) is a perfluorinated sulfonyl fluoride compound characterized by a colorless, volatile liquid form at room temperature. This highly reactive chemical belongs to a broader class of compounds known as perfluoroalkyl sulfonates, which are increasingly being utilized in various advanced chemical reactions. CAS number 375-72-4 uniquely identifies this compound within scientific literature and databases.

NFF is a key player in organic chemistry, particularly for its role in facilitating cross-coupling reactions, such as those catalyzed by palladium. These reactions are essential in the synthesis of more complex molecules from simpler ones, a process critical for creating pharmaceuticals, fine chemicals, and polymers.

Chemical Properties and Mechanism of Action

The nonafluorobutane in NFF refers to a highly fluorinated butyl group attached to a sulfonyl fluoride moiety. The compound is known for its stability, volatility, and immiscibility with water, which makes it suitable for use in organic solvents rather than aqueous environments.

Unlike traditional reagents, such as trifluoromethylsulfonic anhydride, NFF offers significant advantages in terms of cost and stability. The compound’s fluoride leaving group is easily replaced by nucleophiles, including amines, phenolic salts, and enols, allowing for the synthesis of diverse chemical products. This reactivity makes NFF a valuable agent for the creation of sulfonamides, arylsulfonic acids, and alkenyl sulfonic acids, all of which are integral in various chemical industries.

One of the key features that sets NFF apart from other reagents is its speed. Reactions involving NFF can be completed in a matter of seconds, which drastically reduces reaction times compared to other sulfonyl fluoride fluorination agents that can take hours or even days. This rapid reaction rate makes NFF a game-changer in the field of fluorination chemistry.
