Photoreductive debromination of decabromodiphenyl ether by pyruvate

Polybrominated diphenyl ethers (PBDEs) have aroused highly environmental concerns because of their toxicity and ubiquitousness in the biological and environmental system. Here, we report that decabromodiphenyl ether (BDE209) undergoes efficient reductive debromination reaction by pyruvate under UV irradiation (>360 nm). The photoreductive degradation kinetics of BDE209 has been further investigated under different reaction conditions. The debromination reactions occur in a stepwise process, producing a series of lower brominated congeners. The debromination shows unconspicuous position-selective property. The possible photoreductive mechanism has been proposed by UV-vis and kinetic isotope effect (KIE). This study not only provides a potential application of removal of PBDEs contaminations but also provides some information for the fate of PBDEs in environment.

Reductive debromination of decabromodiphenyl ether yields brominated dibenzofurans in a Pschorr-type cyclisation

Brominated dibenzofurans are readily produced from decabromodiphenyl ether by a Pschorr-type cyclisation upon reductive debromination in the absence of good H-donors. DFT-D calculations confirmed that, for polybrominated diphenyl ethers, the reaction is strongly favoured both kinetically and thermodynamically.

PREPARATION OF DECAHALODIPHENYL OXIDE

This invention provides a process of preparing reaction-derived decahalodiphenyl oxide of high purity. The process comprises cofeeding separate feeds of (a) diphenyl oxide and/or partially brominated diphenyl oxide and (b) bromine chloride, bromine chloride and bromine, or bromine chloride and chlorine to a refluxing reaction mixture comprising bromine and at least one Lewis acid bromination catalyst so that high purity decahalodiphenyl oxide is formed.
