摘要：
The process for producing a vic-dichloro acid fluoride compound in a short process and in good yield from the starting material which is inexpensive and readily available is provided. (RH1nullEH1null)CRH2RH3CH2nullOCORHB (I) is fluorinated in a liquid phase to form (CF2ClCFClnullEFF1null) CRF2RF3CF2nullOCORFB (II), and then, an ester bond of the compound (II) is decomposed to form (CF2ClCFClnullEF1null)CRF2RF3COF(III) or the compound (III) and FCORFB (IV).
