Photoreductive debromination of decabromodiphenyl ether by pyruvate

- Efficient reductive debromination of BDE209 by pyruvate under UV irradiation (>360 nm) is presented.
- The debromination reaction appears in a stepwise process and the debromination shows unconspicuous position-selective property.
- Research on mechanism shows that abstracting hydrogen from solvent is not the rate determining step.
