Complementary techniques including laser flash photolysis have been used to investigate the mechanism of decatungstate photocatalyzed oxygenation of methanol in acetonitrile. A particular attention has been directed to determine the most important ch

Previous studies on the mechanism of decatungstate photocatalyzed reactions of aliphatic alcohols and of aromatic hydrocarbons in the presence of oxygen suggest that in the corresponding reactions of aryl alcohols, direct electron transfer can compet

[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 an

A combination of steady-state and time-resolved techniques has been used to investigate the mechanism of the decatungstate (W 1 0 O 3 2 4-) photocatalyzed oxygenation of cyclohexene, and of a series of hexene isomers, as well as of their saturated co
