3-Trifluoromethyl-indoline-2-one derivatives were prepared in a visible light photocatalytic transformation of acrylamides. The arylation-ring closure was initiated by light induced aryl radical generation from aryl diazonium salts with the utilization of erythrosine B as novel organic photocatalyst.
3-Trifluoromethyl-indoline-2-one 衍生物是在丙烯酰胺的可见光光催化转化中制备的。芳基化闭环是通过使用赤藓红 B 作为新型有机光催化剂从芳基重氮盐产生芳基自由基引发的。
