    摘要: 4-Fluorobenzophenone derivatives of 4,4'-difluorobenzophenone are produced by effecting a halogen-fluorine exchanging reaction between the corresponding 4-halogenobenzophenone derivatives or 4,4'-dihalogenobenzophenone and an alkali fluoride.The reaction is carried out by heating in an organic solvent. After distilling off the solvent from the reaction product mixture, the end product is isolated by extracting with a solvent. Alternatively the end product is isolated by distillation.
