Potassium Ferrate A Novel Oxidizing Reagent Based on Potassium Ferrate(VI)
Mechanism + Description
The mechanism for K2FeO4 oxidations is widely agreed to follow the a similar mechanism to that of Chromium (VI) reagents.
K2FeO4 is a widely used oxidant employed in remediation of contaminated waste streams. There are reports of its use synthetically. It reacts in a similar mechanism to Cr (VI) reagents, but without the toxicity or environmental contamination concerns. High cost of commercial material could be a barrier to use, for remediation, it is usually prepared in situ. Solid-supported variants have been reported. Environmentally the reagent produces iron oxides, so it is reasonably benign for the environment.
