Electron Donor–Acceptor Complex Catalysis in Synthetic Chemistry
Angewandte Chemie, EarlyView.Electron donor–acceptor (EDA) complexes are moving beyond stoichiometric photoactivation toward catalytic platforms for radical generation. Productive EDA catalysis requires coordinated donor–acceptor association, charge‐transfer excitation, radical reactivity, and vcatalyst turnover.
