Some fluorine-containing nitrogen acids and their derivatives

Abstract Fluorine-containing nitrogen acids and their derivatives are highly useful compounds in a variety of applications. For example, the acids find practical use as electrolytes or additives for electrolytes in fuel cells, the lithium salt of (CF 3 SO 2 ) 2 NH is being developed for use in batteries, polymeric nitrogen acid electrolytes have been prepared, and the N -fluoro derivatives of some of the nitrogen acids are the most useful electrophilic fluorinating agents available. The first XeN bond was prepared using (FSO 2 ) 2 NH. Interest in these materials has been increasing rapidly over the last 10 years because of the large number of applications in which their physical and chemical properties make them suitable candidates for study.
