From Azides to Nitrogen-Centered Radicals: Applications of Azide Radical Chemistry to Organic Synthesis

Over the last thirty years organic azides have drawn a great deal of attention as radical traps for carbon- and heteroatom-centered radicals, both in intra- and in intermolecular processes. The resulting intermediates (nitrogen-centered radicals such as triazenyls, aminyls, or even iminyls) can be conveniently employed in the synthesis of a variety of cyclic and acyclic nitrogen-containing compounds.
