and alkyl halides using either caesium carbonate in DMF or sodium dimsyl. De-esterification of 2 provided biologically important α-alkyl-α-fluoromethylenebisphosphonic acid, 3, while alkoxide–induced carbon–phosphorusbondcleavage of 2 gave α-fluorophosphonates, 4, which are useful synthons in organic synthesis.
