It is used to convert alcohols into alkyl fluorides and carboxylic acids into acyl fluorides. Aldehydes and ketones do not react with it. The reagent consists of a mixture of N , N -diethyl- 1,1,2,3,3,3-hexafluoropropyl amine and N , N -diethyl- E -pentafluoropropenylamine in varying proportions. The active species is the hexafluoropropylamine; any enamine is converted into this by the hydrogen fluoride byproduct as the reaction proceeds. The reagent is mostly used to convert primary alcohols to alkyl fluorides under mild conditions with high yield. However, secondary and tertiary alcohols give a substantial amount of alkenes and ethers as side products. The amount of enamine in the product depends on temperature control during the reaction — the higher the temperature the more enamine. From Wikipedia, the free encyclopedia.
