Cu-Catalyzed cyanoalkylation of electron-deficient alkenes with unactivated alkyl bromides

Abstract

We here report the photoinduced Cu-catalyzed cyanoalkylation of electron-deficient alkenes by using alkyl bromides as alkylation reagents. In the reactions, 1°, 2°, and 3° unactivated alkyl bromides with various sensitive functional groups were well tolerated with good yields. Notably, terminal and internal alkenes, as well as alkene-containing peptides, were all tolerated well.
