A synergetic copper/photoredox catalyzed ATRA of styrenes and thiosulfonates is developed. Besides aryl ethylenes, the challenging α-substituted styrenes were employed to construct the benzylic quaternary carbon centers. Owing to the mild conditions as well as the high level of substrate compability, this ATRA could be applied to derivatize bioactive natural products in late stage, and to install fluorophores across alkenes. The mechanistic studies reveal sulfonyl radicals as the key intermediate in the transformation.
