Description

2,2'-Dibromobiphenyl is a polybrominated biphenyl (PBB) with two bromine atoms attached to the biphenyl structure.

Uses

PBBs, including 2,2'-dibromobiphenyl, have historically been used as flame retardants in various materials such as plastics for electronics, textiles, and foams. However, due to their environmental persistence and toxicity, the use of PBBs is now restricted or banned in many regions. Chemically, 2,2'-dibromobiphenyl is an important intermediate in organic synthesis. It is utilized in the production of compounds like 5,5-dimethyl-5H-dibenzosilole under specific conditions involving reagents like n-BuLi and solvents such as diethyl ether and hexane. This compound also plays a crucial role in constructing the molecular frameworks of organic luminescent materials and conjugated macromolecules, participating in Suzuki coupling reactions either individually or concurrently through its bromine atoms. Additionally, 2,2'-dibromobiphenyl is employed in copper-catalyzed synthesis of carbazole derivatives through double C-N coupling reactions with amines, and in nickel-catalyzed electroreductive syntheses of triphenylenes, showcasing its versatility and importance in advanced synthetic methodologies.
