Herein, an oxygen atom deletion strategy via sequential Pd-catalyzed decarboxylative carbonylation of carbonates and carbamates to afford esters and amides is reported. Operating under low pressures (near stoichiometric or substoichiometric), either ¹³C labeled products are accessed or a proof-of-concept that CO₂ formed upon decarboxylation can be reduced in situ and reincorporated as CO is shown.

碳酸苄酯和氨基甲酸酯的低压羰基化在 13C 同位素标记和催化 CO2 还原中的应用

在此，报道了通过碳酸酯和氨基甲酸酯的连续 Pd 催化脱羧羰基化以提供酯和酰胺的氧原子删除策略。在低压（接近化学计量或亚化学计量）下操作，可以获取¹³ C 标记的产品，也可以证明脱羧时形成的 CO ₂可以原位还原并重新结合为 CO。
