用途と製造
応用分野
用途有機合成用試薬。
使用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.
一般的な説明1,3-Dibromobenzene undergoes solid-supported [KF-Al2O3] palladium-catalyzed polyarylation reaction with phenyl boronic acid under microwave irradiation to yield conjugated polyaryls.
