We have presented a visible-light mediated, iodine catalyzed radical cascade sulfonylation/cyclization reaction by employing iodine as catalyst without addition of any of photocatalyst and oxidant. A number of sulfone-containing coumarin derivatives with different substituent and functional groups were obtained in moderate to good yields. Besides, the practicality and utility of this protocol were demonstrated by the scale up synthesis. Furthermore, [a] Prof. B.

The visible-light-photocatalysis driven denitrogenative/ radical 1,3-shift of benzotriazole to generate unusual aromatic amine radical and then construct diverse of 3-aryl-aminoquinoxalin-2(1H)-one that bear great synthetic value was disclosed. This photocatalytic reaction...
