Abstract
Comprehensive Summary The visible light‐driven C2 or C3 amination of indoles without any additives was initiated via electron donor‐acceptor (EDA) complex formed by indole and N ‐aminopyridinium salt. This method was compatible with a wide range of substrates and could proceed smoothly without the addition of any photocatalysts, transition‐metal catalysts, or bases. A variety of studies were carried out to examine the presence of EDA complex.
