Triethyl phosphite is an organophosphorus compound with the formula P(OCH2CH3)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 The molecule features a pyramidal phosphorus(III) center bound to three ethoxide groups. Its 31P NMR spectrum features a signal at around +139 ppm vs phosphoric acid standard. Triethylphosphite is prepared by treating phosphorus trichloride with ethanol in the presence of a base, typically a tertiary amine: PCl3 + 3 EtOH + 3 R3N → P(OEt)3 + 3 R3NH + Cl−In the absence of the base, the reaction affords diethylphosphite ((EtO)2P(O)H).
