Method of selective fluorination
The present invention is a method for selectively fluorinating various methylenephosphonate and methylenephosphorane derivatives using an electrophilic fluorinating agent, such as N-fluoro 1,4-diazabicyclo[ 2.2.2]octane by fluorinating the monohalogenated methylenephosphonate or methylenephosphorane...

| Zusammenfassung: | The present invention is a method for selectively fluorinating various methylenephosphonate and methylenephosphorane derivatives using an electrophilic fluorinating agent, such as N-fluoro 1,4-diazabicyclo[ 2.2.2]octane by fluorinating the monohalogenated methylenephosphonate or methylenephosphorane derivative to produce fluoromethylenephosphonate or fluoro-methylenephosphorane derivatives useful as fluorinated Horner-Emmons or Wittig reagents in producing selectively fluorinated vinylic compounds. |
