Abstract

Résumé/Abstract 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 ...
