Tuning the reactivity of an osmium-peroxo unit by modulating metallacycle aromaticity

Zhihong Deng et al. Chem Commun (Camb). .

Abstract

The reactivity of an osmium-peroxo unit supported by a metallacycle is enhanced upon diminishing metallacycle aromaticity. The less aromatically stabilized osmium-peroxo complex is readily protonated and converts selectively to an osmium-hydroxo complex. This work provides a strategy for tuning the reactivity of metal-oxygen species.
