A scalable and operationally simple decarboxylative trifluoromethylation of (hetero)arenes with easily accessible C₆F₅I(OCOCF₃)₂ under photoredox catalysis has been developed. This method is tolerant of various (hetero)arenes and functional groups. Notably, C₆F₅I is recycled from the decarboxylation reaction and further used for the preparation of C₆F₅I(OCOCF₃)₂. The combination of photoredox catalysis and hypervalent iodine reagent provides a practical approach for the application of trifluoroacetic acid in trifluoromethylation reactions.

全氟芳烃碘（III）三氟乙酸的可见光光氧化还原脱羧，用于（杂）芳烃的CH三氟甲基化

已经开发了在光氧化还原催化下具有易于获得的C ₆ F ₅ I（OCOCF ₃）₂的可扩展且操作简单的（杂）芳烃的脱羧三氟甲基化。该方法可耐受各种（杂）芳烃和官能团。值得注意的是，C ₆ F ₅ I从脱羧反应中再循环并进一步用于制备C ₆ F ₅ I（OCOCF ₃）₂。光氧化还原催化和高价碘试剂的结合为三氟乙酸在三氟甲基化反应中的应用提供了一种实用的方法。
