Regioselective 1,2-Di(hetero)arylation of Activated and Unactivated Alkenes with (Hetero)aryl Chlorides
View through CrossRef
Aryl chlorides are more commercially available and lower cost compared with aryl bromides and iodides. However, the use of (hetero)aryl chlorides as aryl radical precursors for the di(hetero)arylation of alkenes remains an underdeveloped area. Furthermore, existing examples of theses reactions are predominantly confined to activated alkenes. In this study, we introduce a benzophenone-catalyzed 1,2-di(hetero)arylation process that is applicable to both activated and unactivated alkenes, utilizing (hetero)aryl chlorides and cyanoarenes as aryl sources. Importantly, this method allows for the simultaneous introduction of two heterocycles to alkenes with high regioselectivity.
