Electroreductive ring-opening carboxylation of styrene carbonates with CO₂ to achieve dicarboxylic acids and/or β-hydroxy acids has been developed via the selective cleavage of the C(sp³)–O bond in cyclic carbonates. The product selectivity is probably determined by the stability and reactivity of the key benzylic radical and carbanion intermediate.

环状碳酸酯与二氧化碳的电化学开环羧化反应

通过选择性裂解环状碳酸酯中的 C(sp ³ )–O 键，开发了苯乙烯碳酸酯与 CO ₂的电还原开环羧化以获得二羧酸和/或β-羟基酸。产物选择性可能由关键的苄基和碳负离子中间体的稳定性和反应性决定。
