Abstract

The present invention relates to a process of preparing N-benzenesulfonimides comprising reacting an alkali metal salt of a sulfonimide with fluorine in the presence of water or water/organic solvent mixtures. N-fluorosulfonimides are useful as fluorinating agents. The N-fluorosulfonimides allow the introduction of fluorine into organic compounds under mild conditions.
