Applicazioni

Dimethyl methylphosphonate is used as a catalyst and a reagent in organic synthesis for the conversion of esters to ketophosphonates. It is an additive for the synthesis of unsaturated polyester resin which has flame retardant high phosphorous and UV-cured epoxy acrylate. It finds application as hydraulic fluids as well.

Note

Incompatible materials strong oxidizing agents and strong bases.

Letteratura

The lithio-derivative reacts with esters to give ß-ketophosphonates, useful precursors of ɑß-unsaturated ketones by Horner-Wadsworth-Emmons olefination: J. Am. Chem. Soc., 88, 5654 (1966). An intramolecular version leads to cyclopentenones: Synth. Commun., 5, 1 (1975); Tetrahedron Lett., 22, 257 (1981). Dimethyl glutarate gives the 3-(phosphonatomethyl)cyclohexenone, olefination of which affords the corresponding 3-alkenylcycloalkenone. Dimethyl succinate also gives this reaction, but in lower yield; higher diesters give acyclic products: J. Org. Chem., 59, 1943 (1994):
