Acylation of -phosphoranium salts with -acyl chlorides gives the corresponding -perfluoro betaine in high yield. Subsequent chlorination or bromination regiospecifically yields the α,α-dihalofluoromethyl perfluoroalkyl ketones. ... -acyl chlorides are available from Aldrich, SCM, or Fluorochem. ...
