Capture of Electrochemically Generated Fleeting Carbazole Radical Cations and Elucidation of Carbazole Dimerization Mechanism by Mass Spectrometry

, 2020
The capture of reactive intermediates is important for the elucidation of reaction mechanisms. We report the first observation of electrochemically generated, short-lived radical cations of carbazole (t1/2 ≈ 97 μs) and two N-substituted carbazole ...

Amorphous Conjugated Carbazole Trimers for Photorefractive Materials

, 2016
New conjugated carbazole trimers for photorefractive materials have been synthesized by Pd-catalytic coupling reaction. These trimers were demonstrated to be amorphous by both differential scanning calorimeter and X-ray diffraction.

Oxidation of Carbazole.

Journal of Synthetic Organic Chemistry, Japan, 1965
In the oxidation of carbazole, two isomers of dicarbazyl are formed as main reaction products. 3, 3'-Dicarbazyl is formed by bichromate or permanganate oxidation in acetic acid, whereas 9, 9'-dicarbazyl is formed by permanganate oxida tion in acetone.
