摘要

在光氧化还原/HAT双催化下，开发了苄基氯与CO2的羧化反应。反应可以在室温下用蓝色LED光源进行。甲酸钾（HCO2K）用作绿色还原剂，催化量的硫代酚酸钠（PhSNa）用作HAT试剂。产生强还原性的二氧化碳自由基阴离子（CO2‧–）以促进C–Cl键的断裂。

Photoredox/HAT dual-catalyzed carboxylation of benzyl chlorides with CO2 using thiophenolate and formate as reductants

Carboxylation of benzyl chlorides with CO₂ has been developed with photoredox/HAT dual-catalysis. The reaction could be conducted at room temperature with blue LED light source. Potassium formate (HCO₂K) is used as a green reductant and a catalytic amount of sodium thiophenolate (PhSNa) is applied as the HAT reagent. Strongly reductive carbon dioxide radical anion (CO₂^‧–) is produced to promote the cleavage of C–Cl bond.
