Six-Membered Aromatic Polyazides: Synthesis and Application

Aromatic polyazides are widely used as starting materials in organic synthesis and photochemical studies, as well as photoresists in microelectronics and as cross-linking agents in polymer chemistry. Some aromatic polyazides possess high antitumor activity, while many others are of considerable interest as high-energy materials and precursors of high-spin nitrenes and C₃N₄ carbon nitride nanomaterials. The use of aromatic polyazides in click-reactions may be a new promising direction in the design of various supramolecular systems possessing interesting chemical, physical and biological properties. This review is devoted to the synthesis, properties and applications of six-membered aromatic compounds containing three and more azido groups in the ring.

Azides – Diazonium Ions – Triazenes: Versatile Nitrogen-rich Functional Groups

For more than 100 years, nitrogen-rich compounds such as azides, diazonium ions, and triazenes have proved to be extremely valuable. Because these functional groups can be easily introduced into various substrates, they are frequently used nowadays. More importantly, they can be converted into a great number of other functional groups. The scope of this article is thus to summarize possible synthetic routes for the formation of these functional groups as well as to highlight some of the most prominent applications of these exciting moieties in chemical biology and combinatorial chemistry. Many of the most famous name reactions such as the Staudinger reduction, Staudinger ligation, Sandmeyer reaction, Wallach reaction, Mitsunobu reaction, Huisgen reaction, Balz–Schiemann reaction, Meerwein arylation, Pschorr reaction or Gomberg–Bachmann reaction are covered.
