Direct phosphonylalkylidenephosphinylation of nucleophiles is achieved by one-pot mono dialkylphosphonoalkylation of dichlorophosphates or methylphosphonic dichloride followed, in situ, by nucleophilic substitution of the chlorine atom of the alkylidenediphosphorylated intermediate.

Synthetic mimics of InsP8, Nature's most phosphorylated inositol phosphate, interact differentially with the kinase PPIP5K2 and provide stabilised, complementary tools to investigate this orphan signal.
Optimum conditions for the solid–liquid phase alkylation of tetraethyl methylenebisphosphonate are dependent on the nature of the alkyl halide. The benzylation with benzyl bromide takes place efficiently in boiling acetonitrile in the presence of potassium carbonate and a phase transfer catalyst. The ethylation with ethyl iodide was best accomplished under solventless microwave conditions in the presence
