Electrochemical oxidation of ferricyanide

Abstract
Abstract We report the electrochemical oxidation of ferricyanide, [Fe III (CN) 6 ] 3− and characterised the oxidation product by in-situ FTIR and XAS spectroelectrochemistry methods. Oxidation of [Fe III (CN) 6 ] 3− is proposed to proceed via a tentative Fe(IV) intermediate that undergoes reduction elimination to give cis-[Fe III (CN) 4 (CH 3 CN) 2 ] 1− as stable product in acetonitrile. Speciation of the oxidation product by DFT calculations is underpinned by good agreement to experimental data.
