Palladiumerium(IV) Oxide-Catalyzed Oxidative Synthesis of N-(2-Pyridyl)indoles via C--H Activation Reaction

An interesting protocol for the synthesis of N-(2-pyridyl)indoles based on a palladiumerium(IV) oxide-catalyzed oxidative C--H activation reaction has been developed. By using alkynes and N-phenylpyridin-2-amines as substrates, the corresponding indoles were isolated in moderate to excellent yields.... Full description
