Visible-light induced 1,2-dicarbofunctionalization of alkenes with quinoxalin-2(1H)-ones and malonic esters

Visible-light photoredox catalyzed 1,2-arylalkylation of alkenes with quinoxalin-2(1 H )-ones and malonic esters has been developed through direct C(sp 2 )–H/C(sp 3 )–H functionalization under mild conditions.
