Oxidation and Homolytic Coupling Regioselectivity of Carbazole in Acidic Media

摘要

Using voltammetric technique with a rotating disk electrode, the anodic oxidation of carbazole in aqueous H_2SO_4- ethanol mixtures was shown to proceed under diffusion and electron transfer control conditions. Electro-oxidation involves one electron transfer; electrode passivation occurs due to the formation of a poorly soluble product. By means of the SCF MO LCAO INDO, AM1-UHF and PM3-HUF Methods, oxidative coupling regioselectivity for carbazole has been Elucidated.
