The EDA complex activation strategy for photochemical synthetic applications. a The principles of EDA complex activation and synthetic use enabled by light. b In situ generated catalytic intermediates can form an intermolecular EDA complex with a substrate. c A catalyst, adorned with an electron-rich unit, reacts with a substrate to generate an electron-poor intermediate prone to intramolecular EDA complex formation.
