An efficient Rh(iii)-catalyzed ortho-selective C–H activation and tandem oxidative olefination-cyclization of aryl sulfonamides is described. The protocol has been applied to various substrates with good functional group tolerance.

Alkene aminoarylation with arylsulfonylacetamides via a visiblelight-mediated radical Smiles–Truce rearrangement represents a convenient approach to the privileged arylethylamine pharmacophore traditionally generated by circuitous, multistep sequences. Herein, we report detailed synthetic, spectroscopic, kinetic, and computational studies designed to interrogate the proposed mechanism, including the
