| abstract |
The invention concerns a method for preparing mono- or difluorinated hydrocarbon compounds. The inventive method for preparing mono- or difluorinated hydrocarbon compounds from an alcohol or a carbonylated compound includes reacting one of them with a fluorinating reagent, optionally in the presence of a base. The invention is characterized in that the fluorinating agent is a reagent comprising a pyridinium motif corresponding to formula (F), wherein R<SUB>0</SUB> represents an alkyl or cycloalkyl group. |
