Organophotocatalytic Arene Functionalization: C-C and C-B Bond Formation

Organophotocatalytic C C and C B bond formation reactions of aryl halides have been developed in the presence of an organophotosensitizer, 3,7 di ( [1,1'-bipheny1]-4-y1)-10-(4-(trifluoromethyl)pheny1)-10H-phenoxazine that has highly negative reduction potential at its photoexcited state. The developed reaction conditions are mild and allow the intermolecular C C bond formation of the generated aryl radical with electron-rich (hetero)arenes and C B bond formation with bis(pinacolato)diboron.
