| Abstract: |
Acetyl hypofluorite, made easily from diluted fluorine and AcONa is very efficient in fluorinating anionic centers. Compounds containing the moieties−CH2SO2−or−COCH2PO−react with bases to create the corresponding anions which can react with AcOF to produce derivatives containing either the CHFSO2−or−COCHFPO−group. Larger excess of base and AcOF result in the difluoro compounds containing the−CF2SO2−or−COCF2PO−sub-structures. The fluorinations proceed fast and smoothly and usually with very good yield even when the base is dissolved in aqueous solution as is the case with K2CO3 or NaHCO3. [ABSTRACT FROM AUTHOR] |
