The protonation of acyllithiumreagents generated in situ from alkyllithiums and carbon monoxide in the presence of dichloromethane or dichloroarylmethanes produces α,α-dichloroalcohols in high yields. The reaction produces α-hydroxy-ketones in high yields when the aryl group of dichloroarylmethane contains a strong electron-donating group at the ortho or para position. The transformation of α,α-dichloro-α-aryl
