abstract: |
This thesis presents site-selective Suzuki-Miyaura reactions of 2,3,5-tribromo-thiophene,
2,4,5-tribromothiophene and 2,3,5-tribromo-N-methylpyrrole, which are controlled by
steric and electronic parameters. Palladium-catalyzed Heck reactions of brominated
thiophenes, N-methylimidazole, N-methylpyrrole and N-methylindole are also presented.
The products were transformed by subsequent 6π-electrocyclization and dehydrogenation
to functionalized benzothiophenes, dibenzothiophenes, benzimidazoles, indoles and
carbazoles, respectively.
