Recent Advances on Radical-Mediated Cyanoalkylation/Cyanation using AIBN and Analogues as the Radical Sources

AIBN (2,2’-azobisisobutyronitrile) and analogues are readily available chemical reagents, known for widely used free radical initiators of polymer chemistry. More importantly, AIBN and derivatives are 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 synthetic community. This review will play a valuable tool in discussing the importance of AIBN and derivatives in the area of synthetic chemistry. In this context, we concluded a comprehensive review that guides readers to recognize AIBN chemistry from several aspects:
1. Introduction
2. Radical addition onto alkenes or alkynes using AIBN as cyanoalkyl radical 
3. AIBN and analogues-mediated Functionalization of C-H bonds
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
