The reaction of aromatic ethers with benzyltrimethylammonium dichloroiodate(1-) in acetic acid in the presence of zinc chloride at room temperature gave iodo-substituted aromatic ethers in good yields.

sequential iron and copper catalysis. Regioselective ortho-activation of anisoles, anilines and phenols was achieved through iron(III) triflimide catalysed iodination, followed by a copper(I)-catalysed, ligand-assisted coupling reaction with N-heterocycle, amide and sulfonamide-based nucleophiles. The synthetic utility of this one-pot, two-step method for the direct amination of ortho-aryl C–H bonds was
