Phosphorus trichloride is an inorganic compound with the chemical formula PCl 3. A colorless liquid when pure, it is an important industrial chemical , being used for the manufacture of phosphites and other organophosphorus compounds .
Thiophosphoryl chloride is an inorganic compound with the chemical formula P S Cl 3. [5] It is a colorless pungent smelling liquid that fumes in air. It is synthesized from phosphorus chloride and used to thiophosphorylate organic compounds, such as to produce insecticides .
Phosphoryl chloride (commonly called phosphorus oxychloride) is a colourless liquid with the formula P O Cl 3. It hydrolyses in moist air releasing phosphoric acid and fumes of hydrogen chloride. It is manufactured industrially on a large scale from phosphorus trichloride and oxygen or phosphorus pentoxide. [4] It is mainly used to make ...

Chemical formula. C 18 H 15 Cl 2 P Molar mass: 333.19 g/mol Melting point: 176 °C (349 °F; 449 K) [1] 85-100 °C [2] ... Phosphorus trichloride Phosphorus pentachloride
Triethylphosphite is prepared by treating phosphorus trichloride with ethanol in the presence of a base, typically a tertiary amine: [1] PCl 3 + 3 EtOH + 3 R 3 N → P(OEt) 3 + 3 R 3 NH + 3 Cl −. In the absence of the base, the reaction of ethanol and phosphorus trichloride affords diethylphosphite ((EtO) 2 P(O)H). Of the many related ...
Near room temperature, the compound degrades to give phosphorus trichloride and an ill-defined phosphorus monochloride: P 2 Cl 4 → PCl 3 + 1/n [PCl] n. The compound adds to cyclohexene to give trans-C 6 H 10-1,2-(PCl 2) 2. [1]
Triphenylphosphite is a precursor to trimethylphosphine, it serves as a source of P 3+ that is less electrophilic than phosphorus trichloride: [1] (C 6 H 5 O) 3 P + 3 CH 3 MgBr → P(CH 3) 3 + 3 "MgBrOC 6 H 5 " Triphenylphosphite is quaternized by methyl iodide: [2] (C 6 H 5 O) 3 P + CH 3 I → [CH 3 (C 6 H 5 O) 3 P] + I −
