Abstract: Spin doesn't matter: A ruthenium(II)-aqua complex bearing a pentadentate pyridylamine with a carboxylate group as a ligand affords a seven-coordinate low-spin (S=0) ruthenium(IV)-oxo complex (see structure) by oxidation through proton-coupled electron transfer. Comparison of the reactivity of the low-spin and an intermediate-spin (S=1) Ru IV-oxo complexes revealed that the spin state does not affect the reactivity of catalytic oxidation of organic compounds. © 2010 WILEY-VCH Verlag GmbH & Co.
