Phosphorus trichloride is commonly used to convert primary and secondary alcohols to the corresponding chlorides. [14] As discussed above, the reaction of alcohols with phosphorus trichloride is sensitive to conditions. The mechanism for the ROH →RCl conversion involves the reaction of HCl with phosphite esters: P(OR) 3 + HCl ⇌ HP(OR) + 3 ...

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 ...
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 ...
Tertiary (3°) phosphines, with the formula R 3 P, are traditionally prepared by alkylation of phosphorus trichloride using Grignard reagents or related organolithium compounds: 3 RMgX + PCl 3 → PR 3 + 3 MgX 2. In the case of trimethylphosphine, triphenyl phosphite is used in place of the highly electrophilic PCl 3: [6]
Organophosphorus chemistry is the scientific study of the synthesis and properties of organophosphorus compounds, which are organic compounds containing phosphorus. [1] They are used primarily in pest control as an alternative to chlorinated hydrocarbons that persist in the environment.
The compound was probably prepared in the 1850s by combining phosphorus trichloride and ethanol, but intentional preparations came later. It arises as follows: [2] PCl 3 + 3 C 2 H 5 OH → (C 2 H 5 O) 2 P(O)H + 2 HCl + C 2 H 5 Cl. Under similar conditions but in the presence of base, triethyl phosphite results: [3]
