Uses |
2,2'-Dibromobiphenyl is used to produce 5,5-dimethyl-5H-dibenzosilole at the temperature of -78 - 20°C. It will need reagent n-BuLi and solvents diethyl ether, hexane. 2,2'-Dibromobiphenyl is a polybrominated biphenyl. Polybrominated biphenyls (PBBs) are a group of 209 synthetic organic compounds with 1-10 bromine atoms attached to biphenyl. They can be used as flame retardants and may be added to the plastics used to make products like computer monitors, televisions, textiles, and plastic foams to make them difficult to burn. However, the use of PBBs is banned or restricted in most areas due to their toxicity and persistence in the environment. (L628, L629) |
