Synthetic method of meta-hydroxyl/methoxyl polybrominated diphenyl ethers

The invention relates to a method for synthesizing meta-OH/MeO-PBDEs, which comprises the following steps: the meta-OH/MeO-PBDEs are obtained by taking 2, 4-dibromophenol or aminophenol and 5-fluoro-2-nitroanisole as a raw material through a series of reactions such as a coupling reaction, nitro gro...

More Information
Summary:The invention relates to a method for synthesizing meta-OH/MeO-PBDEs, which comprises the following steps: the meta-OH/MeO-PBDEs are obtained by taking 2, 4-dibromophenol or aminophenol and 5-fluoro-2-nitroanisole as a raw material through a series of reactions such as a coupling reaction, nitro group reduction, deamination, demethoxylation, bromo-substitution or through a series of reactions such as the coupling reaction, the bromo-substitution, a Sandmeyer reaction, the nitro group reduction, the deamination, the demethoxylation, the bromo-substitution. The method has reasonable reaction conditions and high product purity, and the product purity is usually more than 80 percent. The method has larger practical value to the synthesis of meta-OH/MeO-PBDEs containing more than five bromines(containing five bromines), and provides more standard sample support to the detection of high-bromine PBDE derivatives in the environment. The meta-OH/MeO-PBDEs are generated.
