Description

CAS: 108-36-1 | C6H4Br2 | 235.91 g/mol

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) (PPh3)4 as a reagent. Further, it undergoes solid-supported potassium fluoride-aluminum oxide palladium-catalyzed polyarylation reaction with phenyl boronic acid to get conjugated polyaryls.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Applications
Le 1,3-dibromobenzène est utilisé dans la réaction de couplage de Suzuki pour la préparation de [n]métacyclophanes. Il est utilisé pour préparer de la 5-3-bromo-phényl)-2,4-di-tert-butoxy-pyrimidine en utilisant le Pd(0) (PPh3)4 comme réactif. De plus, il subit une réaction de polyarylation à base solide de fluorure de potassium et d’oxyde d’aluminium catalysée par le palladium avec de l’acide phényl boronique pour obtenir des polyaryles conjugués.

Solubilité
Immiscible avec l’eau.

Remarques
Incompatible avec les agents oxydants forts.
