| | 3,4-Dibromopyridine Usage And Synthesis |
| Uses | 3,4-dibromopyridine is a vital organic compound that could synthesise virous azaindoles. 6-Azaindoles are formed through site-selective Pd-catalyzed Sonogashira reaction of 3,4-dibromopyridine with alkynes, followed by a Pd-catalyzed tandem C–N coupling and cyclization with amines. On the other hand, 5-azaindoles are obtained by a site-selective Pd-catalyzed C–N coupling reaction of 3,4-dibromopyridine with amines, followed by C–C coupling and cyclization with alkynes[1]. | | References | [1] N. Son. “Synthesis of 5- and 6-Azaindoles by Sequential Site-Selective Palladium-Catalyzed C–C and C–N Coupling Reactions.” Synlett 52 1 (2020): 1308–1312.
