Method for synthesizing carbazole derivative
-
Paragraph 0013; 0044-0045, (2021/10/05)
The invention aims to provide a method for synthesizing a carbazole derivative. The method is characterized in that palladium chloride is used as a catalyst, 2, 2' - dibromobiphenyl is used as an electrophilic reagent, primary amine is taken as a nucleophile, and the carbazole derivative is directly cross-coupled under the conditions of toluene as a solvent and an air atmosphere. The method has the advantages of high yield, high selectivity, simplicity and convenience in operation and the like.

Herein, we describe a facile synthesis of N-arylated carbazoles via ladderization of fluorinated oligophenylenes. The reaction consists of two subsequent nucleophilic substitutions triggered by an electronic transfer from dimsyl anions. The reaction allows the effective one-pot formation of at least six C-N bonds with pronounced selectivity to the C-F bond placement.
