Electron exchange rates of cobalt tetra-arylporphines
Abstract
The first accurate direct measurements of electron exchange rates of cobalt (III)-cobalt(II) tetra-phenylporphyrins indicate rate constants of 9·69 dm3 mol–1s–1[outer-sphere for bis(pyridine) complexes] and 2·71 × 104dm3 mol–1s–1(chloride-bridged inner-sphere) in CDCl3.
