Tailoring dicobalt Pacman complexes of Schiff-base calixpyrroles towards dioxygen reduction catalysis

Chem Commun (Camb). 2010 Feb 7;46(5):710-2. doi: 10.1039/b923189g. Epub 2009 Dec 18.

Abstract

By modifying the mouth of a macrocyclic dicobalt Pacman complex, it is possible to both isolate new bridging-superoxo and hydroxyl complexes and to tune the reactivity of this system towards catalytic four-electron reduction of dioxygen to water.
