Hydro-dehalogenation of α-Haloketones by Halogen and Pseudo Halogen, Sulfur and Aromatic Compounds in Combination with Metal Halides

Abstract

α-Haloketones 1 were successfully hydro-dehalogenated to their corresponding ketones 2 by sulfur and aromatic compounds (benzene, aniline and pyridine) in combination with metal halides in tetrahydrofuran. For comparison, α-haloketones 1 were also dehalogenated by metal halides alone in tetrahydrofuran.
