Oxidative photocyclization of 1-phenyl-2-(2-arylethenyl)-3,3-dimethyl-3H-indolium perchlorates leading to 7H-indolo[1,2-a]quinolinium salts was investigated. The synthesis was performed under Vis irradiation. Blue LEDs emitting at 454.5 nm were used as the light source. The reaction progress was followed by UV-Vis spectroscopy. The products were characterized by IR, 1H and 13C NMR spectroscopy. Reaction
