Abstract

AIBN (2,2′-azobisisobutyronitrile) and analogues are readily available chemical reagents that are widely used as free-radical initiators of polymer chemistry. Importantly, AIBN and derivatives are also safe and efficient (alkyl)cyano sources for synthesizing cyano-containing scaffolds. In the past decades, synthetic strategies using AIBN and derivatives as radical sources have attracted increasing attention from the synthetic community. This review will provide a valuable tool for understanding the importance of AIBN and derivatives in the area of synthetic chemistry. In this context, we present a comprehensive review that guides readers through the developments in AIBN chemistry over the past five years from several aspects.

4 Synthesis of Ketone and its Derivatives with AIBN and Analogues as Carbonyl Source

5 Construction of Multi-ring Skeletons in the Presence of AIBN and Analogues

6 Direct Application as Cyano (CN) Source in Cyanation Reactions

7 Conclusions
