Abstract: Benzylic alcohols are oxidized with molecular oxygen to the corresponding carbonyl compounds and carboxylic acids in supercritical carbon dioxide medium in the presence of 2-fluoroanthraquinone as an organic photocatalyst. The transformation is promoted by blue light irradiation at 405 nm. The similar processing of aliphatic terminal 1,3- and 1,4-diols affords the corresponding diacids, while small changes in the procedure allows one to convert butane-1,4-diol into γ-butyrolactone in one experimental step.

Keywords: oxidation, photocatalysis, supercritical carbon dioxide, benzylic alcohols, diols, ketones, aldehydes, lactones.
