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 iodinereagent provides a practical approach
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。
