Graphical Abstract:


Background: The complex photochemistry of aryl azides has fascinated scientists for several decades. Spectroscopists have investigated the intermediates formed by different analytical techniques. Theoretical chemists have explained the intrinsic interplay of intermediates under different experimental conditions.

Objective & Methods: A complete understanding of the photochemistry of a given fluoro aryl azide is a basic requisite for its use in chemistry. In this review, we will discuss the synthesis of several fluoro substituted aryl azides and the reactions and intermediates generated upon photolysis and thermolysis of these azides and some examples of their applications in photoaffinity labeling and organic synthesis.

Conclusion: In spite of the extensive research on the photochemistry of fluoro aryl azides, there are some areas that remain to be investigated. The application of this reaction in the synthesis of novel heterocyclic compounds has not been fully studied. Since fluorophenyl azides are known to undergo C-H and N-H insertion reactions, they could be used to prepare new fluorinated molecules or in the biochemical process known as photoaffinity labeling.

Keywords: Fluoro aryl azides, photochemistry, thermochemistry, photoaffinity labeling, bifunctional photochemical probes, azido fluoroquinolones.
