已经开发出在可见光照射下,在没有任何外部光催化剂的情况下,用市售的三氟甲亚磺酸钠 (CF3SO2Na) 对喹喔啉-2(1H)-酮进行 C-H 三氟甲基化,以中等至优异的产率提供多种 3-三氟甲基喹喔啉-2(1H)-酮。机理研究表明,1O2通过光氧化还原反应过程中的能量转移和单电子转移过程与O2.−共存。
C−H trifluoromethylation of quinoxalin‐2(1H)‐ones with commercially available sodium trifluoromethanesulfinate (CF3SO2Na) under visible light irradiation without any external photocatalyst has been developed, providing a variety of 3‐trifluoromethylquinoxalin‐2(1H)‐ones in moderate to excellent yield. Mechanistic studies have shown that1O2coexists with O2.−through the energy transfer and single‐electron transfer processes during the photoredox reaction.
