Transfer hydrodehalogenation of aryl halides accelerated by a saturated sodium acetate aqueous solution

Abstract

Development of catalytic hydrodehalogenation of halogenated organic compounds is an important topic from the viewpoint of environment protection. Herein, we conducted the first work on the utilization of a saturated aqueous solution of sodium acetate (CH₃COONa) as an efficient and environmentally-friendly reaction medium for transfer hydrodehalogenation of various aryl halides using Pd/C as the catalyst. It was found that the transfer hydrodehalogenation could be accelerated significantly by the saturated CH₃COONa aqueous solution due to the surfactant-similar effect of CH₃COONa and the activation of the C–Cl bond by the dissolved solvated ions.
