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 .
Phosphorus trichloride is a major industrial chemical and widely used starting material for phosphorus chemistry. Phosphorus tribromide is used in organic chemistry to convert alcohols to alkyl bromides and carboxylic acids to acyl bromides (e.g. in the Hell-Volhard-Zelinsky reaction).
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 ]

Phosphorus trichloride (PCl 3) is popular, [12] ... However, the mechanism can also be tetrahedral or S N 1 in highly polar solvents [21] ...
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 .
In polar solvents such as acetonitrile, ... Ph 3 PCl 2 can be obtained by chlorination of triphenylphosphine oxide with, for example, phosphorus trichloride, ...
Thiophosphoryl chloride has tetrahedral molecular geometry and C 3v molecular symmetry, with the structure S=PCl 3.According to gas electron diffraction, the phosphorus–sulfur bond length is 189 pm and the phosphorus–chlorine bond length is 201 pm, while the Cl−P−Cl bond angle is 102°.
