3-Acetoxyquinuclidine as Catalyst in Electron Donor–Acceptor Complex-Mediated Reactions Triggered by Visible Light

3-Acetoxyquinuclidine was found to act as a catalytic electron donor species in a variety of electron donor–acceptor complex-mediated reactions. Only substoichiometric amounts (10–25 mol %) were needed to trigger the desired reaction. The outcome could be tuned by selecting the nature of the formed radical to perform amino- and hydro-decarboxylation, dimerization, and cyclization reactions. Importantly, no external additives were needed in this reaction.
