Reactivity comparison of high-valent iron(iv)-oxo complexes bearing N-tetramethylated cyclam ligands with different ring size

Abstract

The ring size effect of macrocyclic TMC ligands in nonheme iron(iv)-oxo complexes has been examined in hydrogen atom transfer (HAT) and oxygen atom transfer (OAT) reactions; an iron(iv)-oxo complex bearing a smaller TMC ligand is more reactive in both HAT and OAT reactions, resulting from its high Fe IV/III redox potential. © 2013 The Royal Society of Chemistry.
