One-Pot Synthesis of Symmetric and Unsymmetric 1,1-Bis-indolylmethanes via Tandem Iron-Catalyzed C-H Bond Oxidation and C-O Bond Cleavage

The reactions of indoles with ethers give a variety of symmetric and unsymmetric 1,1-bis-indolylmethane derivatives via iron-catalyzed C-H bond oxidation and C-O bond cleavage.
