Special Issue: Photoredox Catalysis

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.
