Gas-Solid Reactions: Photochemical Oxidation of Thioketones in the Crystalline State

Article abstract of DOI:10.1021/jo00184a019

Photochemical oxidation of 11 diaryl thioketones (1-11) was conducted in the solid state.Quite interestingly, of these only six were oxidized to the corresponding carbonyl compound whereas the rest were photostable.However, in solution all were readily oxidized.The difference in behaviour between the thioketones in the solid state has been rationalized on the basis of molecular arrangement in the crystal.X-ray crystal structure analyses of four thioketones were carried out in this connection.
