A straightforward and high-yielding approach to a variety of polycyclic aromatic hydrocarbons has been achieved through palladium-catalyzed annulation of 9,9-dimethyl-9-stannafluorenes and dithienostannole with 1,2-dihaloarenes. In addition, 1,1-dibromo-1-alkenes can also be applied to this annulation to produce dibenzofulvenes in excellent yields. In the experiment, the researchers used many compounds, for example, 2,3-Dibromobenzo[b]thiophene (cas: 6287-82-7Recommanded Product: 6287-82-7).
2,3-Dibromobenzo[b]thiophene (cas: 6287-82-7) belongs to benzothiophene derivatives. Benzothiophene finds use in research as a starting material for the synthesis of larger, usually bioactive structures. Its aromaticity makes it relatively stable, although as a heterocycle, it has reactive sites which allow for functionalization.Recommanded Product: 6287-82-7
