Abstract
Photochemical excitation of (nBu 4N) 4W 10O 32 in the presence of oxygen (760 torr) leads to the formation of C 6H 11 − and OH − radicals which can be revealed by ESR spin-trapping investigations. Cyclohexane is transformed in cyclohexanone and cyclohexanol with an overall photooxidation quantum yield of 0.35 at 325 nm photoexcitation wavelength. A strong influence of oxygen pressure on the concentration ratio of these products is observed; in that, at low oxygen pressure (15 torr), the yield of cyclohexane is negligible and the photocatalytic oxidation of cyclohexane mainly leads to the formation of cyclohexanol. The photocatalyst investigated does not suffer irreversible modifications allowing the oxygenation of cyclohexane by O 2 itself under mild conditions with good turnover values.
