Visible-light-induced C(sp3)-C(sp3) bond formation via radical/radical cross-coupling

Radical/radical cross-coupling remains challenging due to diffusion control issues. Herein, we report a visible-light-induced radical/radical cross-coupling reaction of quaternary ammonium salts and Hantzschs via C-N and C-C bond cleavage. The current synthetic approach furnishes 1,2-diphenylethanes in moderate to good yields and provides a method for the construction of the C(sp(3))-C(sp(3)) bond.
