摘要：
Site-selective C(sp(3))-H alkenylation was achieved under photo-irradiation in the presence of a catalytic amount of decatungstate anion, W10O324-. In this reaction, the radical addition/beta-scission sequence is successfully combined with photocatalytic C(sp(3))-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.
