Decatungstate photocatalyzed oxidation of aryl alkanols. Electron transfer or hydrogen abstraction mechanism?
[reaction: see text] Decatungstate W(10)O(32)(4-) 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.
