摘要：

An enamine-mediated photoredox catalyzed C(sp2)-C(sp3) cross-coupling of dual radical precursors for the arylation of ketone is presented in this Letter. These reactions led to the formation of an enamine by using pyrrolidine to functionalize the C(sp3)-H bond in ketone substrates, which could be smoothly converted to alpha-arylated ketones with inert aryl bromides and even aryl chlorides in moderate to good yields under mild reaction conditions. The photocatalytically induced C(sp2)-C(sp3) cross-coupling between unactivated noncyclic ketones and aryl halides was achieved, and multiple carbonyl alpha-arylated backbones containing various natural products and drug molecules were successfully constructed.
