The alkylation of aryl sulfamates and carbamates using iron catalysis provides synthetically useful yields across a range of substrates. The directing group ability of sulfamates and carbamates, accompanied by their low reactivity toward conventional cross-couplings, renders these substrates useful for the synthesis of polyfunctionalized arenes.
