Photoredox-catalyzed difunctionalization of alkenes through CN coupling and multicomponent radical/polar crossover

We reported an alkyl-thianthrenium salts (TTs) involved three-component radical alkene difunctionalization reaction. Alkylation of anilines has been realized via this mild method. An oxidative radical/polar crossover may be involved in the strategy, which realizing the combination of polar chemistry and radical chemistry. A variety of anilines, primary alkyl-substituted TTs, secondary alkyl-substituted TTs and olefins could be accessed in medium to good yield. Our work provides a valuable approach to producing diverse functionalized aniline derivatives.
