Herein, a photocatalytic strategy for the synthesis of succinic acids by alkene dicarboxylation with carbon dioxide (CO2) and formate salt as synergistic carbon sources is described. The formate salt acts as both a C1 source and reductant in the reaction with catalytic amount of 1,4-diazabicyclo[2.2.2]octane (DABCO) as a hydrogen atom transfer reagent. Various mono-, di-, and trisubstituted alkenes

dicarboxylation of diverse alkenes, including simple styrenes. The highly competing hydrocarboxylation side reaction was successfully overridden. Good yields of products were obtained undermild reaction conditions at ambient temperature and pressure of CO2. The dual role of formate salt may stimulate the discovery of a range of new transformations undermild and friendly conditions.
