“…In 2019, Ohmiya and Nagao et al reported a novel NHC-catalyzed decarboxylative radical coupling reaction of aryl aldehydes and N -(acyloxy)phthalimides that produces diverse aryl alkyl ketones via a SET process between the enolate form of Breslow intermediate and the redox N -(acyloxy)phthalimides . Very recently, elegant NHC-catalyzed radical reactions involving Breslow-centered radical cation intermediates have been well developed by the groups of Studer, Scheidt, Chi, Ye, Ohmiya, Huang, Wang, Du, Li, Yan, and other research groups. , Inspired by these remarkable works, we envisioned that the efficient synthesis of β-ketonitriles could be realized through NHC-catalyzed radical reactions. Additionally, azobis(isobutyronitrile) (AIBN) and its derivatives as commercially available, less toxic, and effective cyanation reagents have attracted considerable attention in organic chemistry .…”
