Direct C(sp²)-H alkylation of unactivated arenes enabled by photoinduced Pd catalysis.

ABSTRACT: Despite the fundamental importance of efficient and selective synthesis of widely useful alkylarenes, the direct catalytic C(sp²)-H alkylation of unactivated arenes with a readily available alkyl halide remains elusive. Here, we report the catalytic C(sp²)-H alkylation reactions of unactivated arenes with alkyl bromides via visible-light induced Pd catalysis. The reaction proceeds smoothly under mild conditions without any skeletal rearrangement of the alkyl groups. The direct syntheses of structurally diverse linear and branched alkylarenes, including the late-stage phenylation of biologically active molecules and an orthogonal one-pot sequential Pd-catalyzed C-C bond-forming reaction, are achieved with exclusive chemoselectivity and exceptional functional group tole
