A new route to alpha-alkyl-alpha-fluoromethylenebisphosphonates (2) has been developed starting from commercially available tetraethyl fluoromethylenebisphosphonate (1), and alkyl halides using either cesium carbonate in DMF or sodium dimsyl. De-esterification of 2 provided biologically important alpha-alkyl-alpha-fluoromethylenebisphosphonic acid (3), while alkoxide–induced carbon–phosphorus bond cleavage of 2 gave alfa-fluorophosphonates (4), which are useful synthons in organic synthesis.
