| | 1,3-Dibromobenzene Usage And Synthesis |
| Chemical Properties | clear colourless to light yellow liquid | | Uses | 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. | | Definition | ChEBI: A dibromobenzene carrying bromo groups at positions 1 and 3. | | General Description | 1,3-Dibromobenzene undergoes solid-supported [KF-Al2O3] palladium-catalyzed polyarylation reaction with phenyl boronic acid under microwave irradiation to yield conjugated polyaryls. |
