Phosphonic esters are prepared using the Michaelis–Arbuzov reaction. For example, methyl iodide catalyses the conversion of trimethylphosphite to the phosphonate ester dimethyl methylphosphonate: P(OMe) 3 → MePO(OMe) 2. These esters can be hydrolysed to the acid (Me = methyl): MePO(OMe) 2 + H 2 O → MePO(OH) 2 + 2 MeOH
Organophosphate flame retardants are part of a wider family of phosphorus-based agents which include organic phosphonate and phosphinate esters, in addition to inorganic salts. [ 56 ] [ 57 ] When some prominent brominated flame retardant were banned in the early 2000s phosphorus-based agents were promoted as safer replacements.

The general structure of a phosphite ester showing the lone pairs on the P. In organic chemistry, a phosphite ester or organophosphite usually refers to an organophosphorous compound with the formula P(OR) 3. They can be considered as esters of an unobserved tautomer phosphorous acid, H 3 PO 3, with the simplest example being trimethylphosphite ...
Triethyl phosphite (TEP) is an organophosphorus compound, specifically a phosphite ester, with the formula P(OCH 2 CH 3) 3, often abbreviated P(OEt) 3. It is a colorless, malodorous liquid. It is used as a ligand in organometallic chemistry and as a reagent in organic synthesis.
Triethyl phosphonoacetate is a reagent for organic synthesis used in the Horner-Wadsworth-Emmons reaction (HWE) or the Horner-Emmons modification.. Triethyl phosphonoacetate can be added dropwise to sodium methoxide solution to prepare a phosphonate anion.
Dimethylphosphite is an organophosphorus compound with the formula (CH 3 O) 2 P(O)H, known as dimethyl hydrogen phosphite (DMHP). Dimethylphosphite, is a minor tautomer of the phosphorus(V) derivative.
