In 2019,Journal of Organic Chemistry included an article by Mallick, Sudesh; Maddala, Sudhakar; Kollimalayan, Kalidass; Venkatakrishnan, Parthasarathy. Product Details of 6825-20-3. The article was titled 《Oxidative Coupling of Carbazoles: A Substituent-Governed Regioselectivity Profile》. The information in the text is summarized as follows:
Oxidative C-C coupling of carbazoles possessing various substituents is demonstrated in the presence of organic (metal-free) recyclable oxidants, such as DDQ or CA/H+, for accessing bicarbazole regioisomers. Differently substituted carbazoles are examined to showcase regioselective discrimination (3,3′- vs. 1,3′-bicarbazoles) and preferences based on sterics and electronics in oxidative coupling. Finally, a mechanism that involves the carbazole radical cation has been traced (evidenced) and proposed on the basis of the UV-vis-NIR absorption and EPR spectroscopy results. This study underlines the strategic chem. preparation of a series of bicarbazoles in an efficient manner. The experimental part of the paper was very detailed, including the reaction process of 3,6-Dibromo-9H-carbazole(cas: 6825-20-3Product Details of 6825-20-3)
3,6-Dibromo-9H-carbazole(cas: 6825-20-3) is used as a pharmaceutical intermediate, and also an important intermediate of synthesizing optoelectronic materials. It has been used as a reagent in the synthesis of P7C3-A20 which is a potent neuroprotective agent.Product Details of 6825-20-3
