rare example of EDA photochemistry in a catalytic regime. The synthetic utility is demonstrated through visible light-driven radicaltrifluoromethylation and Minisci alkylation reactions. The scalability of the EDA complex-promoted reaction is evidenced by the successful multigram-scale trifluoromethylation of methyl N-Boc pyrrole-2-carboxylate in a continuous flow manifold.

Recent advances in synthetic chemistry have seen a resurgence in the development of methods for visible light-mediated radical generation. Herein, we report the development of a photoactive ester based on a quinoline N-oxide core structure, that provides a strong oxidant in its excited state. The heteroaromatic N-oxide provides access to primary, secondary, and tertiary radical intermediates, and its
