The debromination reaction of α-bromomethylketone compounds was achieved by using water as the hydrogen source under the catalysis of HBr. Using α-bromomethylketones as raw materials, tetrahydrofuran as solvent, when the molar ratio of α-bromomethylketone to 5% mass fraction hydrobromic acid was 1.0:0.2, the debrominated product could be obtained with a isolated yield of 94% [high performance liquid chromatography (HPLC) yield 96%] by reacting at 180 ℃ for 5~14 h. All products were confirmed by1H NMR and 13C NMR spectra.

Key words: α-bromomethylketone, HBr, debromination
