Abstract: The invention provides a process for producing a fluorine-containing compound from an inexpensive material. Namely, Compound I such as RACH2OH is reacted with Compound II such as XCORB to form Compound III such as RACH2OCORB, followed by fluorination in a liquid phase to form Compound IV such as RAFCF2OCORBF, which is converted to Compound V such as RAFCOF and/or Compound VI such as RBFCOF. RA is an alkyl group or the like, RB is a perhalogenoalkyl group or the like, RAF and RBF are fluorinated RA and RB, and X is halogen.
