Highlights•In situ NMR spectroscopy was employed to monitor oxidative conversion of cyclohexanone by hydrogen peroxide and Keggin-type phosphomolybdates.•UV-Vis spectroscopy was used to identify the various reduced and oxidized phosphomolybdate species.•Activation of the substrate via ketonic-enolic tautomerism was evidenced as the primary step.•Peroxomolybdate-type complexes were identified as active species for oxidation process.
