Publisher SummaryThis chapter focuses on the chemistry of carbazoles. The reactions of the nucleus, introduction of substituents on carbazole nitrogen, reactions involving n-substituents, introduction of substituents onto carbazole carbon, and reactions involving c-substituents, outline the chemical properties of the carbazoles. The chapter also describes the methods for the synthesis of carbazoles. The method that has been most utilized for the preparation of aromatic carbazoles from noncarbazole precursors is the dehydrogenation of a tricyclic indole, usually a 1, 2, 3, 4-tetrahydrocarbazole. In addition, precursors such as biphenyls with an ortho nitrogen substituent, the diphenylamines, two separate six-membered ring components, and indoles are used for the synthesis of carbazoles.
