摘要：
A photoredox-catalyzeddivergent 1,2-dicarbonylation and hydroacylationof alkenes with acid anhydride is presented. This approach offersa mild and efficient entry to 1,4-dicarbonyl compounds bearing all-carbonquaternary centers, exhibiting a broad substrate scope and high functionalgroup compatibility. Hydrocarbonylaltion of alkenes can also be realizedby simply introducing a proton source to the reaction system. Mechanisminvestigations support a radical addition/radical-polar crossovercascade.
