A Low‐Spin Ruthenium(IV)–Oxo Complex: Does the Spin State Have an Impact on the Reactivity?

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) RuIV–oxo complexes revealed that the spin state does not affect the reactivity of catalytic oxidation of organic compounds.
