Synthesis of Phosphate Monoesters

The following paper presents an efficient and environmentally friendly method for producing phosphate monoesters, in which the only byproduct is water, as opposed to a different reaction, which also gives off pyridine hydrochloride as a byproduct.
The paper describes that it was experimentally determined that the best solvent, tertiary amine, and catalyst (or nucleophilic base) for the reaction are DMF-nitroethane, tributylamine, and N-butylimidazole, respectively, each giving the highest yield. This is a summary of the main reaction discussed in the paper.
* The article states that water was constantly removed by azeotropic reflux, so that the reverse reaction was prevented.

I have also included an interesting extensive study on phosphate monoesters.

  • It is a good example but fix:
    1) your citations are incomplete in CiteULike
    2) butyl misspelled in a few places
    3) the reaction you drew is reversible - what prevents the water from reacting with the phosphate ester?

  • Full marks. Fix the spelling of azeotropic in your text.
