Abstract

Here we present our development of the super Lewis acid, iron(III) triflimide as an activating agent of N-halo- and N-thioaryl succinimides for the regioselective functionalization of arenes. We also describe how the iron(III)-catalyzed halogenation reactions were further exploited by combination with copper(I)-catalyzed Ullmann-type coupling reactions for the development of one-pot, multistep processes, including intermolecular aryl C–H amination. This Account also illustrates intramolecular versions of these one-pot processes for the preparation of benzannulated heterocycles, as well as the application of these methods for the synthesis of biologically active compounds and natural products.
