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. It is toxic and reacts readily with water to release hydrogen chloride.

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 ]
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]
Phosphorus(II) halides may be prepared by passing an electric discharge through a mixture of the trihalide vapour and hydrogen gas. [ citation needed ] The relatively stable P 2 I 4 is known to have a trans , bent configuration similar to hydrazine and finds some uses in organic syntheses, the others are of purely academic interest at the ...
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.
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 ...
In polar solvents such as acetonitrile, Ph 3 PCl 2 adopts an ionic phosphonium salt structure, [Ph 3 PCl +]Cl −, [3] whereas in non-polar solvents like diethyl ether it exists as a non-solvated trigonal bipyramidal molecule. [4] Two [Ph 3 PCl +] species can also adopt an unusual dinuclear ionic structure—both interacting with a Cl − via ...
