Site-selective C(sp3)-H alkenylation was achieved under photo-irradiation in the presence of a catalytic amount of decatungstate anion, W10O324−. In this reaction, the radical addition/β-scission sequence is successfully combined with photocatalytic C(sp3)-H functionalization. The reaction using weaker C−H bonds such as those in THF revealed that the benzenesulfonyl radical itself underwent HAT directly from the C−H bond, and a decatungstate anion participated in a chain-repairing step. (Figure presented.).
