Scaled Photochemical Reactions: A continuous flow approach for the photochemical synthesis of β-ketonitriles and related species is presented. This approach tolerates (hetero)aromatic substrates and uses readily available TBADT as an effective HAT catalyst reaching throughputs of up to 41 mmol/h.

Unactivated C(sp<sup>3</sup>)–H Bond Functionalization of Alkyl Nitriles with Vinylarenes and Mechanistic Studies
The first example of a metal-free unactivated C(sp(3))-H bond functionalization of alkyl nitriles with terminal vinylarenes to provide gamma-ketonitrile derivatives is described. This protocol features simple operations, a broad substrate scope, and atom and step economy. In addition, Cu-catalyzed C(sp(3))-H bond functionalization of azodi-isobutyronitrile (AIBN) and analogues with terminal vinylarenes to generate gamma-ketonitriles was also studied. A preliminary free-radical pathway was confirmed by capturing an alkyl radical, and a conjugate system was found that can stabilize radical intermediates and be in favor of this transformation. Density functional theory (DFT) calculations also provide important evidence of the free-radical pathway.
