N-fluoropyridinium salts have been shown to be stable fluorinating reagents with the ability to fluorinate a variety of organic compounds. For example, T. Umemoto et al., "N-fluoropyridinium Triflate and Its Derivatives: Useful Fluorinating Agents", Tetrahedron Letters 27(37), 4465 (1986) report that these salts are useful in the fluorination of aromatic compounds and the conversion of enol silyl ethers to alpha-fluoroketones. T. Umemoto et al., "Base-Initiated Reactions of N-fluoropyridinium Salts; A Novel Cyclic Carbene Proposed as a Reactive Species", Tetrahedron Letters 28(24), 2705 (1987) report that N-fluoropyridinium salts can also be converted in to useful pyridine derivatives such as 2-chloropyridine.

This compound is useful in fluorinating organic compounds including aliphatic compounds such as 1-octyl magnesium bromide and enolate derivatives such as 3-pentanone enol acetate; alicyclic compounds such as 1-morpholino-1-cyclohe-ene, 1-morpholino-1-cyclopentene, 2-carboethoxy cyclopentanone and cyclohexanone trimethyl silyl enol ether; and aromatic compounds such as benzene and anisole.
