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 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°.
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 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 ).
Phosphinous acids are usually organophosphorus compounds with the formula R 2 POH. They are pyramidal in structure. Phosphorus is in the oxidation state III. Most phosphinous acids rapidly convert to the corresponding phosphine oxide, which are tetrahedral and are assigned oxidation state V.
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]
In chemistry, phosphorochloridites are a class of organophosphorus compound with the formula (RO) 2 PCl (R = organic substituent). They are pyramidal in shape, akin to regular phosphites (P(OR) 3 ). They are usually colorless and sensitive toward hydrolysis and, to some extent, oxidation to the corresponding phosphorochloridates ((RO) 2 P(O)Cl).
