Anwendungen

1,3-Dibromobenzene is used in Suzuki coupling reaction for the preparation of [n]metacyclophanes. It is used to prepare 5-(3-bromo-phenyl)-2,4-di-tert-butoxy-pyrimidine using Pd(0) (PPh<sub>3</sub>)<sub>4</sub> as a reagent. Further, it undergoes solid-supported potassium fluoride-aluminum oxide palladium-catalyzed polyarylation reaction with phenyl boronic acid to get conjugated polyaryls.

Bemerkungen

Incompatible with strong oxidizing agents.
