使用

3,6-Dibromocarbazole is used as a pharmaceutical intermediate, and also an important intermediate of synthesizing optoelectronic materials. It has been used in the preparation of N-(2-hydroxyethyl)-3,6-dibromocarbazole.

一般的な説明

Lithiation of 3,6-dibromocarbazole with n-butyllithium has been studied.

合成

3, 6-dibromocarbazole is synthesized with three methods, such as N-bromosuccinimide method, liquid bromine method and silica gel method. But now main method for synthesis is silica gel method. The main raw materials used in the synthesis include carbazole, N-bromosuccinimide, solvent methylene chloride, catalyst silica gel, and the yield could reach 89.5%.
