Triphenyl phosphite is prepared from phosphorus trichloride and phenol in the presence of a base:
PCl₃ + 3 HOC₆H₅ → P(OC₆H₅)₃ + 3HCl
Trimethyl phosphine is prepared from triphenylphosphite:
3 CH₃MgBr + P(OC₆H₅)₃ → P(CH₃)₃ + 3 MgBrOC₆H₅

Reported in EPA TSCA Inventory.

Poison by intraperitoneal and subcutaneous routes. Moderately toxic by ingestion. An experimental eye and severe human skin irritant. Combustible when exposed to heat or flame. To fight fire, use CO₂, mist, dry chemical. When heated to decomposition, it emits toxic fumes of PO_x. See also Phenol.

  Triphenyl phosphite , with CAS number of 101-02-0, can be called phosphorous acid, triphenyl ester ; Advance TPP ; Phenyl phosphite ; Sumilizer TPP-R ; Trifenoxyfosfin ; Tris(phenoxy)phosphine . It is a colourless to pale yellow liquid, be insoluble in water. Triphenyl phosphite (CAS NO.101-02-0) are susceptible to form highly toxic and flammable phosphine gas in the presence of strong reducing agents, such as hydrides. Partial oxidation may result in the release of toxic phosphorus oxides.
