ResumoThe preparation of 2,2'-bipyridylchromium peroxide, pyridinechromium peroxide, and chromium peroxide etherate is described. 2,2'-Bipyridylchromium peroxide converts different classes of alcohols to the carbonyl compounds. In 1,2-diols C—C bond cleavage occurs extensively. α-Hydroxy acids are decarboxylated quantitatively. Oximes are converted to their carbonyl compounds and thiols to their disulfides, dihydroxy phenolic compounds to quinones, benzyl amine to benzaldehyde, aromatic amines to their azo compounds, anthracene and phenanthrene to their quinones. Pyridinechromium peroxide converts different classes of alcohols efficiently to the carbonyl compounds, thiols to their disulfides, anthracene to anthraquinone. Mandelic and benzilic acids are decarboxylated very efficiently. Chromium peroxide etherate is an efficient reagent for the oxidation of different classes of alcohols to their carbonyl compounds.
