Photoactivation of Electron Donor–Acceptor Complexes for C(sp2)–H Amination of Arenes Using an Organocatalytic Acceptor

from the combination of pyridine and either LiOTf or HOTf. The reactions proceed with irradiation using 370 nm LEDs, and the pyridine/acid acceptor can serve as a catalyst under aerobic conditions. This represents a rare example of a catalytic acceptor in EDA photochemistry.
