Photochemical excitation of (nBu4N)4W10O32 in the presence of oxygen (760 Torr) leads to the formation of C6H11. and OH. radicals which can be revealed by ESR spi-trapping investigations. Cyclohexane is transformed in cyclohexanone and cyclohexanol with an overall photooxidation quantum yield of 0.35 at 325 nm. A strong influence of oxygen pressure on the concentration of these products is observed
