Ferric chloride catalyzed direct conversion of carbonyl compounds to the corresponding chloride with silicon hydride (dichloromethylsilane, chlorodiphenylsilane or trichlorosilane) was realized. In the presence of PBr3 or NaI, ferric chloride-catalyzed deoxygenative halogenation of carbonyl compounds also took place smoothly to give the corresponding bromide or iodide in moderate to good yields.

Key words: reductive halogenation, carbonyl compound, FeCl3, dichloromethylsilane
