Progress of Dialkyl Azodicarboxylates in Organic Transformations

In recent past, dialkyl azodicarboxylates have been embraced as versatile reagents in synthetic strategies other than Mitsunobu reactions. These azo compounds have been utilized as an oxidant or dehydrogenating reagent in oxidative transformations, such as cross dehydrogenative coupling, oxidative Ugi‐type reaction, dehydrogenation etc. Moreover, they have been utilized in different types of bond construction like C‐Heteroatom (C‐Het) and S−N bond. Very recently, these azo compounds have also been explored in photochemical reactions. Such types of reported reactions and their reaction pathways are presented here in this minireview, which manifested the oxidative abilities and advantageous features of dialkyl azodicarboxylates. An all‐rounder reagent. A brief summary of recent organic transformations mediated by dialkyl azodicarboxylates, popularly known for Mitsunobu reaction, is given in this minireview. Moreover, synthetic procedures and reaction pathways of these selected reactions are also highlighted.
