Dialkylphosphonoflouracetylchlorides are used to introduce directly the 2-oxophosphonate 1-fluorinated synthons on organometallic reagents.A Horner reaction of the 3 derivated anions with aldehydes gave various 2-fluoro-2-enones.Application to the cis, trans caronaldehyde ethyl ester led to the 2-fluoroethenyl pyrethroid derivatives.

The acylation of organocuprates or organolithiated reagents with 2-dialkylphosphonoalkanoyl chlorides or dialkylphosphonofluoroacetyl chlorides represents a general and efficient route to β-ketophosphonates.A Horner reaction between the lithiated anions derived from α-fluoro-β-ketophosphonates and aldehydes leads to 2-fluoro-2-enones whereas the lithiated anions derived from γ-acetylenic-β-ketophosphonates afford enynones. β-ketophosphonate / 2-dialkylphosphonoalkanoyl chloride / dialkylphosphonofluoroacetyl chloride / 2-fluoro-2-enone / enynone
