Pentafluorophenylmagnesium bromide reacted with trichloro-, dichloro-, chlorodifluoro-, bromo-, and trifluoro-acetaldhyde to form the corresponding halogenomethylpentafluorophenylmethanols. These alcohols on oxidation afforded ketones, which underwent haloform cleavage, whilst with phosphorus pentachloride they gave the expected chloropentafluorophenylethanes in good yield.
