without any additives was initiated via electrondonor-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.
A palladium-/copper-catalyzed intermolecular C-H amination reaction of indoles has been developed. This reaction proceeds in good to excellent yields to produce a variety of 2-amino-substituted indoles and exhibits excellent regioselectivity at room temperature. Furthermore, chloroamination of indoles provides a simple method for the construction of C-N and C-Cl bonds in one step.
