Peroxide Dianion Finds A Stable Home

Using hydrogen bonds to stabilize peroxide dianion in a macrocycle provides a metal-free source of a useful oxidant
Department: Science & Technology
Keywords: cryptand, hydrogen bonding, peroxide

Like a hermit crab occupying an abandoned seashell, the transient peroxide dianion (O22–) has been enticed by researchers at Massachusetts Institute of Technology to take up residence in a hydrogen-bonding macromolecule (Science, DOI: 10.1126/science.1212678). Generating stable, soluble sources of O22– has historically been a challenge in dioxygen chemistry. Reduction of O2 to O22– is typically carried out in chemical and biochemical oxidation processes by . . .
