Iron-Catalyzed Oxidative Coupling of Benzylamines and Indoles: Novel Approach for Synthesis of Bis(indolyl)methanes

A novel route for synthesis of bis(indolyl)methanes has been developed by the oxidative coupling of benzylamines and indoles in the presence of iron(II) triflate as a catalyst and molecular oxygen as an oxidant. This method promises versatility, cost-effectiveness, and efficiency.
