The oxidation of d -myo-inositol (Myo) by CrVI yields the inosose and Cr3+ as final products when an excess of cyclitol over CrVI is used. The redox reaction takes place through the combination of CrVI → CrIV → CrII and CrVI → CrIV → CrIII pathways. Intermediacy of CrIV was evidenced by the detection of CrO 2 2 + , formed by reaction of CrII with O2. The EPR spectra show that five- and six-coordinated oxo-CrV intermediates are formed, with the cyclitol acting as bidentate ligand. Penta-coordinated oxo-CrV species are present at any [H+], whereas hexa-coordinated ones are only observed at pH |
