|Abstract:||The photoreduction of 2-acetonaphthone by (Bu)_3SnH and (Bu)_3SiH were investigated by the method of flash photolysis and compared with the results obtained from the steady state method. The rate constant of the reduction by (Bu)_3SnH was found to be 1.3×10^6/mole^-1 sec^-1, which is close to that of Linschitz et al. The temperature dependence of the rate constant gives the activation energy of 1.7kcal mole^-1. The reduction by (Bu)_3SiH was found not to occur even after a long exposure to sunlight. Furthermore we discuss qualitatively about the activation energy and the reactivity of reducing agents.|
