Methylphosphonic acid

Methylphosphonic acid is an organophosphorus compound with the chemical formula. CH3P(O)(OH)2. The phosphorus center is tetrahedral and is bonded to a methyl group, two OH groups and an oxygen. Methylphosphonic acid is a white, non-volatile solid that is poorly soluble in organic solvent but soluble in water and common alcohols.

Methylphosphonic acid is a white, non-volatile solid that is poorly soluble in organic solvent but soluble in water and common alcohols. Methylphosphonic acid can be prepared via the Michaelis-Arbuzov reaction from triethylphosphite: The dialkylphosphonate is then treated with chlorotrimethylsilane: The siloxyphosphinate is then hydrolyzed:
