Carbon-Nitrogen bond-forming reactions of diakyl azodicarboxylate: A promsing synthetic strategy

Azodicarboxylates have found applications in electrophilic amination reactions and in pericyclic reactions. The nucleophilic trigger in Mitsunobu reactions, that is, the zwitterion formed from triphenylphosphine and dialkyl azodicarboxylate, has been utilized recently in various heterocyclic constructions. This Focus Review summarizes the potential utility of azodicarboxylates in various carbon-nitrogen bond-forming reactions.
