Decatungstate W10O324- photosensitized oxidation of a series of para-X-substituted 1-aryl-1-alkanols was investigated. The only oxidation product of the side-chain of the 1-aryl-1-alkanol was the aryl ketone. The product analysis and kinetic data of the title reaction support a hydrogen atom transfer mechanism in the rate-determining step.
