一般描述
4,4′-Dibromooctafluorobiphenyl undergoes lithiation with n-butyllithium to yield 4,4′-dilithiooctafluorobiphenyl and 4-lithio-4′-bromooctafluorobiphenyl.
应用
4,4′-Dibromooctafluorobiphenyl was used as internal standard to determine brominated flame retardants in sediment samples using on-line combination of pressurised hot water extraction and liquid chromatography-gas chromatography.
